Log Message:
Update p5-MooseX-ClassAttribute to 0.26.

Changes from previous:
0.26   2011-06-06
- The default() method for class attributes always returned a value, even if
  the default was a subroutine ref, which isn't how the method works for
  regular attributes. This broke inlining with Moose HEAD.

0.25   2011-06-05
- Class attributes now have a definition context set, which means that errors
  thrown from generated methods associated with these attributes say something
  like "X at accessor MyClass::ClassAttribute (defined at path/to/file line
  42)" rather than "generated method (unknown origin)".

0.24   2011-02-22
- This release provides forward compatibility with Moose 1.99+. It will still
  work with Moose 1.23 as well. Partially based on work originally done by
  Moritz Onken.

0.23   2011-02-13
- Fixed a bug where applying a role with class attributes didn't record the
  role as actually being applied in the meta class (or role) to which it was
  applied. Reported by Karen Etheridge. RT #59610.
- Applying multiple roles to a class lost all class attributes from those
  roles. Fixed by Andrew Rodland. RT #59572.

0.22   2011-02-02
- Explicitly require namespace::clean 0.20 to avoid some bad interactions
  between namespace::clean and Package::Stash.

0.21   2010-10-29
- Switch from Test::Exception to Test::Fatal.

0.20   2010-10-07
- A test file tried to load MooseX::Role::Parameterized, which was not listed
  as a dep. Reported by Andreas Koenig. RT #61957.

0.19   2010-10-06
- Removed references to MooseX::ClassAttribute::Meta::Method::Accessor, which
  was removed in 0.18. This caused lots of test failures if you hadn't
  installed a previous version of this distribution.

0.18   2010-10-05
- Changes to work with (and require) Moose 1.15.

0.17   2010-09-26
- Changes to work with (and require) Moose 1.09.
