* Support unicode emojis and remove emojify.js
This PR replaces all use of emojify.js and adds unicode emoji support to various areas of gitea.
This works in a few ways:
First it adds emoji parsing support into gitea itself. This allows us to
* Render emojis from valid alias (😄)
* Detect unicode emojis and let us put them in their own class with proper aria-labels and styling
* Easily allow for custom "emoji"
* Support all emoji rendering and features without javascript
* Uses plain unicode and lets the system render in appropriate emoji font
* Doesn't leave us relying on external sources for updates/fixes/features
That same list of emoji is also used to create a json file which replaces the part of emojify.js that populates the emoji search tribute. This file is about 35KB with GZIP turned on and I've set it to load after the page renders to not hinder page load time (and this removes loading emojify.js also)
For custom "emoji" it uses a pretty simple scheme of just looking for /emojis/img/name.png where name is something a user has put in the "allowed reactions" setting we already have. The gitea reaction that was previously hard coded into a forked copy of emojify.js is included and works as a custom reaction under this method.
The emoji data sourced here is from https://github.com/github/gemoji which is the gem library Github uses for their emoji rendering (and a data source for other sites). So we should be able to easily render any emoji and :alias: that Github can, removing any errors from migrated content. They also update it as well, so we can sync when there are new unicode emoji lists released.
I've included a slimmed down and slightly modified forked copy of https://github.com/knq/emoji to make up our own emoji module. The code is pretty straight forward and again allows us to have a lot of flexibility in what happens.
I had seen a few comments about performance in some of the other threads if we render this ourselves, but there doesn't seem to be any issue here. In a test it can parse, convert, and render 1,000 emojis inside of a large markdown table in about 100ms on my laptop (which is many more emojis than will ever be in any normal issue). This also prevents any flickering and other weirdness from using javascript to render some things while using go for others.
Not included here are image fall back URLS. I don't really think they are necessary for anything new being written in 2020. However, managing the emoji ourselves would allow us to add these as a feature later on if it seems necessary.

because the CSS was lazy-loaded the rules in arc-green did not win.
included the css file in the main bundle to fix. the black dots can not
be fixed via CSS because they are drawn in a `<canvas>` element
unfortunately.
- introduced window.config to help with js-based lazy-loading
- adjusted webpack chunk naming to avoid 'vendors~name.js' that webpack
defaults to for vendor chunks.
- added theme class to html and prefixed all selectors. this is
neccesary so that the theme styles win over the lazy-loaded ones.

loadCSS was used as a polyfill for rel=preload but it seems we only used
it on a single CSS file which did not help much. Changed the icon CSS to
a blocking load and preload the woff2 variants which does work in modern
browsers (Firefox currently needs the network.preload about:config
setting but should gain proper support soon).

This changes the CSS output of webpack to output to the public/css
directory instead of inling CSS in JS. This enables CSS minification and
autoprefixer based on browserslist which would otherwise not be
possible.
The result of this change is two new output files currently:
- public/css/swagger.css
- public/css/gitgraph.css

Currently, this needs to be its own chunk because fomantic depends
on jQuery being present. The next step is to move fomantic to webpack
too after which we can combine the index,fomantic and jquery files into
one.
jquery-migrate is still neccessary because our ancient version of Dropzone
seems to break without it. I imagine it can be removed after a Dropzone
upgrade.

Created a second webpack output file for swagger-ui which is loaded on
the /api/swagger route. One notable difference is the absence of the
swagger favicon that was previously used which is now the gitea icon. I
see no easy way to restore that favicon, so I decided to not keep it.
* move semantic.dropdown.custom.js to webpack
Also disabled a annoying linter rule which insisted that imports can not
contain a file extension.

* reorganize web_src files and rebuild
* restart ci
- moved gitgraph.js to web_src and made it importable and es6-compatible
- created new webpack chunk for gitgraph
- enabled CSS loader in webpack
- enabled async/await syntax via regenerator-runtime
- added script to ensure webpack chunks are loaded correctly
- disable terser's comment extraction to prevent .LICENCE files
gitgraph.js has many issues:
1. it is incompatible with ES6 because of strict-mode violations
1. it does not export anything
1. it's css has weird styles like for `body`
1. it is not available on npm
I fixed points 1-3 in our version so it's now loadable in webpack. We should eventually consider alternatives.
* js: Import Semantic-UI's dropdown.js (version 2.3.1)
* js: Set tabindex=-1 on dropdown items
Setting tabindex=-1 on focusable elements within dropdown menus allows
the user to treat dropdown menus as a single focusable item with its own
internal navigation using arrow keys.
* js: Don't use jQuery to click menu items
Menu items are often <a> elements, which jQuery refuses to trigger click
events on. Instead it just bubbles up to the menu.
Using HTMLElement's click method fixes this and makes menu items
clickable from the keyboard using dropdown menus.
* js: Set correct ARIA 1.1 roles on dropdown menus
Setting role= makes assistive technology aware there is a widget here.
In this case, Orca will now exit browse mode and allow us to capture
keydown events when focused on a dropdown menu. It will also inform the
user that there's a menu focused.
Since dropdowns can be used in multiple elements each with different
ARIA roles, a guessRole method is used to find the correct role.
All roles I consider possible are listed, but only menu is implemented.
* js: Set aria-expanded when dropdown menus show and hide
This is deliberately done before the transition finishes so that screen
readers get immediate feedback.
* js: Set aria-label or aria-labelledby on dropdown menus
This makes dropdown menu buttons screen reader accessible.
aria-labelledby refers to an element using an ID, so the chosen labels
are now assigned a unique ID- This ID is not stable, do not refer to it
with user scripts.
* js: Set aria-activedescendant on dropdown menus
As the menus grab focus and navigate by tracking a 'selected' div class,
assistive technology has no idea that what the current selection is.
Assign IDs to each menu item and set aria-activedescendant to the ID of
the currently selected menu item.
When the menu is unfocused, remove aria-activedescendant- This isn't
neccessary but in my experience it triggers Orca to remind the user of
their current selection when re-focusing the menu.
* Makefile: Make eslint ignore semantic.dropdown.js
This file is taken from Semantic UI which isn't linted upstream.
Ignore it as we won't fix these issues.
