Incompatible with DocPad v6.80 and above

Plugin requires updating to CoffeeScript v2. This can be done automatically via running https://github.com/bevry/boundation on it.
If you would like the DocPad team to do it, then transfer the repo to the https://github.com/docpad organisation, and run the following:

npm owner add balupton docpad-plugin-cleancss
npm owner add bevryme docpad-plugin-cleancss

[balupton]

master is now working, @RobLoach can you please npm owner add bevryme docpad-plugin-cleancss to it, so CI can publish it https://travis-ci.com/github/docpad/docpad-plugin-cleancss/jobs/368504982

[balupton]

ok, bevry now has maintainership, however tests are failing, which will require a volunteer to fix
