Thalia fe3165faff build: Add csshint, jshint and jscs to math extension
Also adds the corrections made to various js files when jscs
was run, and removes an old version of .jshintrc. Only
VisualEditor files are checked by csshint due to clashes with
an upstream bug in the csslint parser. This could be looked
into in the future.
