lessCSS

With the leafo/lessPHP project defunct, the Less PHP compiler has been switched to the gpeasy/LessPHP project, version 1.7.0.2. The new engine supports more, if not all, of the newest Less features like extends, mixin guards, etc. More information on the project website. As always, please check any of your existing less files for compatibility.

Also, thanks to MODX forum user Magnatron for the request to update path-fixing functions to ignore data: URLs.
