Update from version 0.70 to version 0.72.

Upstream changes:
0.72 Mon, February 23, 2009
    * Moose::Object
    * Moose::Meta::Method::Constructor
      - A mutable class accepted Foo->new(undef) without complaint,
        while an immutable class would blow up with an unhelpful
        error. Now, in both cases we throw a helpful error
        instead. Reported by doy.

0.71_01 Sun, February 22, 2009
    * Moose::Cookbook
      - Hopefully fixed some POD errors in a few recipes that caused
        them to display weird on search.cpan.org.

    * Moose::Util::TypeConstraints
      - Calling type or subtype without the sugar helpers (as, where,
        message) is now deprecated.
      - The subtype function tried hard to guess what you meant, but
        often got it wrong. For example:

         my $subtype = subtype as 'ArrayRef[Object]';

        This caused an error in the past, but now works as you'd
        expect.

    * Everywhere
      - Make sure Moose.pm is loaded before calling
        Moose->throw_error. This wasn't normally an issue, but could
        bite you in weird cases.

0.71 Thu, February 19, 2009
    * Moose::Cookbook::Basics::Recipe11
      - A new recipe which demonstrates the use of BUILDARGS and
        BUILD. (Dave Rolsky)

    * Moose::Cookbook::Roles::Recipe3
      - A new recipe, applying a role to an object instance. (Dave
        Rolsky)

    * Moose::Exporter
      - Allow overriding specific keywords from "also" packages. (doy)

    * Tests
      - Replace hardcoded cookbook tests with Test::Inline POD
        to ensure they don't get out of sync. (Dave Rolsky)

    * Moose::Cookbook
      - Working on the above turned up a number of little bugs in the
        recipe code. (Dave Rolsky)

    * Moose::Util::TypeConstraints::Optimized
      - Just use Class::MOP for the optimized ClassName check. (Dave
        Rolsky)
