Revision history for Perl extension Starch.

0.04 2015-07-21

 - Update state's in_store if the store did not find any data.  This
   should provide some minor performance improvements and correct
   behavior.
 - Moved the hash_seed and generate_id methods into the manager.
 - Renamed invalid key to no_store key, which means its named
   after what it causes rather than what it is used for (an anti-
   pattern of sorts, but this key will be used for more general
   purpose stuff).
 - Added a mark_dirty method to state.
 - Moved stringify_key and key_separator from manager to store.
 - Increase test coverage.

 - Better Carp handling by setting Starch modules as Internal so that
   the caller information ends up in the user's code.
 - Move state ID validation up to the Manager so it is easier for
   integration libraries to validate the ID.
 - Lots of documentation re-jiggery (still not 100% satisfied).

0.02 2015-07-16

 - Remove all uses of DEMOLISH, they were causing race conditions in
   some cases during global destruction.  Good by LogUnsaved and AutoSave
   plugins.  :(
 - Fix Type::Tiny union constraints sometimes failing on Perl < 5.14.
