Subject: [PATCH] Transition *.css to compiler plugins

Note that we will need to execute our plan to bump the isopack/unibuild
formats and do careful backwards compatibility in order for published
packages containing these css sources to still be usable by existing
versions of Meteor.  (This also will include bumping compiler.BUILT_BY.)
