Support less files

[marekvyroubal]

Is possible to add support for file type less?
Thanks

Unfortunately the Autoprefixer library (which this extension use) does not support Less or SASS. I'm looking into detecting CSS file changes (#35) to be able to work in tandem with preprocessors but it is not done yet.

If you need it right now I would go for a task runner like Gulp or Grunt to handle both preprocessing and autoprefixing.
