Add Stylus lexer

[yoshuawuyts]

It would be awesome to have support for Stylus. A duplicate issue has been opened on the Stylus issue page.

You'll want to look at github/linguist and at upstream Pygments itself — we'll add lexers when they land in Pygments!

upstream pygments has 71 open pull requests and 139 outstanding issues. Might it make sense to maintain pygments.rb as a true fork and add in only upstream activity as it's needed? Shouldn't be too difficult to keep up seeing as there's only been about 50 commits in the last year on Pygments.
