Add correct versions of Bootstrap 3 & Font Awesome to the repository

There doesn't appear to be any version-locking mechanism in place for
frontend assets, and the Bootstrap 3 JS files, Font Awesome font
files and GlyphIcons font files are already hard-committed to the
repository. Therefore, I think it makes sense for the less files for
bootstrap 3 and font-awesome to be hard-committed too. This ensures that
anyone doing frontend testing will be using the exact same version of
these assets.
