Added Perl to the list of languages

Added Perl into bugs ahoy, for Bugzilla and  bugzilla.mozilla.org.
Changed SimpleMapping to a component mapping

Added component mapping so that both BMO and Bugzilla products and
their relevant components would show up for the Bugzilla checkbox,
since they use more languages than just Perl and good first bugs will
be tagged with the language. Also added a more info snippet for
Bugzilla.
Fix simple mappings for Bugzilla and BMO.
