Curtis Jewell's Perl stuff

I had a documentation patch for Moose (actually in Moose::Error::*) and got walked through using git in order to commit through their repo quite nicely on irc://irc.perl.org/moose.

I know that my next patch for them will be to Moose::Manual::Contributing, however. (Nothing bad, just that it assumes you've been using git for more than 20 minutes in a few places. Is why I needed walked through it!)
