OPTIONS requests and not implemented methods.

[dim0xff]

Hello!

I've made some changes.

_return_not_implemented

Catalyst::Action::REST::_return_not_implemented was returning message with real subroutine name, so everyone can see it. I think it should be visible only for developers, but not for end users. End users should see requested URI.

OPTIONS request method

OPTIONS request method should return in Allow header only subroutines, which have "method part" in uppercase.
A little example for explanation:

sub test_sub : Local : ActionClass('REST') { ... }
sub test_sub_GET : Private { ... }
sub test_sub_MY_GET : Private { ... }
sub test_sub_post : Private { ... }

So response for OPTIONS request should return the next Allow header:

Allow: GET MY_GET

PS: sorry for my English :-)
