Added sass compilation ftw
Move custom metalsmith plugins to /plugins
Downgraded grunt-sass because of node-sass#337, add jshinting and cleaning of tmp directories
No need to compile to a tmp directory for CSS, thus no need to clean
Renamed and included github hljs styling as a sass partial
Cleanup
New jshint reporter
Ugly; recompile sass on each build
Add author metadata and sort the collection by date
