* Cleaning up public/ and documenting js/css libs.
This commit mostly addresses #1484 by moving vendor'ed plugins into a
vendor/ directory and documenting their upstream source and license in
vendor/librejs.html.
This also proves gitea is using only open source js/css libraries which
helps toward reaching #1524.
* Removing unused css file.
The version of this file in use is located at:
vendor/plugins/highlight/github.css
* Cleaned up librejs.html and added javascript header
A SafeJS function was added to templates/helper.go to allow keeping
comments inside of javascript.
A javascript comment was added in the header of templates/base/head.tmpl
to mark all non-inline source as free.
The librejs.html file was updated to meet the current librejs spec. I
have now verified that the librejs plugin detects most of the scripts
included in gitea and suspect the non-free detections are the result of
a bug in the plugin. I believe this commit is enough to meet the C0.0
requirement of #1534.
* Updating SafeJS function per lint suggestion
* Added VERSIONS file, per request
