The io/ioutil package has been deprecated as of Go 1.16, see
https://golang.org/doc/go1.16#ioutil. This commit replaces the existing
io/ioutil functions with their new definitions in io and os packages.

Introduce 'make svg' which calls a node script that compiles svg files
to `public/img/svg`. These files are vendored to not create a dependency
on Node for the backend build.
On the frontend side, configure webpack using `raw-loader` so SVGs can
be imported as string.
Also moved our existing SVGs to web_src/svg for consistency.
