Update p5-Moose from version 0.79 to version 0.80.

Upstream changes:
0.80 Sat, Jun 6, 2009
    * Moose::Manual::FAQ
      - Add FAQ about the coercion change from 0.76 because it came up
        three times today (perigrin)
        - Win doy $10 dollars because Sartak didn't think anybody
          would document this fast enough (perigrin)

    * Moose::Meta::Method::Destructor
      - Inline a DESTROY method even if there are no DEMOLISH methods
        to prevent unnecessary introspection in
        Moose::Object::DEMOLISHALL

    * Moose::*
      - A role's required methods are now represented by
        Moose::Meta::Role::Method::Required objects. Conflicts are now
        represented by Moose::Meta::Role::Method::Conflicting
        objects. The benefit for end-users in that unresolved
        conflicts generate different, more instructive, errors,
        resolving Ovid's #44895. (Sartak)

    * Moose::Role
      - Improve the error message of "extends" as suggested by Adam
        Kennedy and confound (Sartak)
      - Link to Moose::Manual::Roles from Moose::Role as we now have
        excellent documentation (Adam Kennedy)

    * Tests
      - Update test suite for subname change in Class::MOP
        (nothingmuch)
      - Add TODO test for infinite recursion in Moose::Meta::Class
        (groditi)
