Merge branch 'master' into exception_interface

master: (112 commits)
The warning about a class having mutable ancestors has been removed (and was never in a non-dev Moose release)
Work with old and new Moose
Preserve immutable_options when temporarily making a class mutable
Rework the C<< $c->go >> documentation a little, hopefully it's more clear.
Blargh. Merge branch deprecate_appclass_actions manually, with svn merge http://dev.catalyst.perl.org/repos/Catalyst/Catalyst-Runtime/5.80/trunk http://dev.catalyst.perl.org/repos/Catalyst/Catalyst-Runtime/5.80/branches/deprecate_appclass_actions . after I forgot -l on svk push, but ctrl-C after the first rev meant svk had already committed a merge mark and re-merging did nothing, and removing it didn't do the right thing. Fail cake..
Eat the merge mark, svk hates me.
