to allow use as an instance method to make this work.
Implemented Mouse::Role::override and ::super. To do this, added
Mouse::Meta::Class->add_override_method_modifier,
Implemented throwing stubs for Mouse::Role::augment and ::inner, as in
Moose::Role.
Added 020_roles/ tests from latest respoitory version of Moose.
Modified some tests to pass; the rest have been moved to
020_roles/failing for later examination.
Implemented Mouse::Role->does_role, from Moose. This does not yet
quite seem to pass all the tests it should, not sure why.
Fixed bug in Mouse::Meta::Role->apply and ->combine_apply, so that
030_roles/002_role.t tests pass.
Implemented ->version, ->authority and ->identifier in Mouse/Utils.pm,
imported for use as methods by Mouse::Meta::Role and
Mouse::Meta::Class.
Tweaked .gitignore.
"make test" passes all tests, including the new ones.

+[15:29] <stevan> kolibrie: please write a test
+[15:29] <stevan> I am not exactly sure who should win either,.. but I suspect it is not working correctly right now
