Re: issues gogits/gogs#2863 and gogits/gogs#3231
As a result of modifications to the contents of the conf folder, `make bindata`
was run, causing an update to bindata.go.

This commit will be rebased onto the 'develop' branch.
This commit improves templates readability, since all of them use consistent
indent with all template command blocks indented too.
1. Indents both HTML containers such as <div>, <p> and Go HTML template blocks
such as {{if}} {{with}}
2. Cleans all trailing white-space
3. Adds trailing last line-break to each file
The "PHP" formatting function doesn't add anything, except an undocumented date format.
All usages in the templates have been replaced with DateFmtShort and DateFmtLong for convenience.
