angerwhale hacking

so, I hacked around on angerwhale and I ported it from Crypt::OpenPGP to Crypt::GpgME. These changes are available on my github fork, specific changes are here. The fork has a few other chang es, including moving from NEXT to Class::C3 next::method and making it send text/html for IE. The IE 'patch' added another dependency, Catalyst::Plugin::Browser, which is really just a nice wrapper around HTTP::BrowserDetect. I also decided to bump the requirement for Catalyst itself to 5.8.
