[Catalyst] Documentation bug in Catalyst::Request

[Toby Corkindale]

Bug in Catalyst::Request.
It says:
  $req->action
       Returns the requested action as a Catalyst::Action object.


However, it just returns the "action", (ie. foo/bar).
To get a genuine Catalyst::Action object, you need to call $c->action.
I'd want to keep backwards compatibility, so maybe note in C::R that the method
returns the equivelent of $c->action->action, and that you might want to
investigate calling $c->action if you want a Catalyst::Action object.
