Subject: [PATCH] Add matches for ruby modules

Similar to what's already done for Perl. Existing rules only match shebangs,
which is not useful in most cases. This was tested to yield no false
positives when run against every perl and python source file I could find
on my system (260 CPAN modules and 59 Python modules). Produces a couple
of false negatives for a couple of files from 30 Ruby gems I have
installed, but is still an improvement over existing rules. (Ruby is
used to construct DSLs quite often, it would be really tricky to match
those).
