Update to 1.002000

Upstream changes:
1.002000 - 2013-05-04
  - add 'moosify' attribute key to provide code for inflating to Moose
  - fix warnings about unknown attribute parameters on metaclass inflation
  - don't pass 'handles' down when doing 'has +' to avoid unDWIMmy explosions
  - throw a useful exception when typemap doesn't return a value
  - avoid localising @_ when not required for Sub::Quote
  - successfully inflate a metaclass for attributeless classes (RT#86415)
  - fix false default values used with non-lazy accessors
  - stop built values that fail isa checks still getting stored in the object
  - stop lazy+weak_ref accessors re-building their value on every call
  - make lazy+weak_ref accessors return undef if built value isn't already
    stored elsewhere (Moose compatibility)
  - stop isa checks being called on every access for lazy attributes
  - bump Devel::GlobalDestruction dependency to fix warning on cleanup
    when run under -c (RT#78617)
  - document Moose type constraint creation for roles and classes
    (actually fixed in 1.001000)
