First pass LESS files (compiles to workless.min.css)

Not perfect by any means - but does work and compiles with no errors.
Next step is work on mixins and reduce the code footprint.
Shaves 5KB off the minified CSS.

Up to you entirely if you want to include it - I'll continue to update myself as I find it really useful.


(Sorry last pull request was to your master branch, I've cancelled that and opted for develop)
