New issue 3053: PostgreSQL HSTORE type should be marked hashable = False

Gunnlaugur Þór Briem:

The `HSTORE` type returns `dict` objects, which are not hashable, so it should not have the default `hashable = True`. Fixing this (setting `hashable = False`) allows columns of this type to be loaded along with ORM entities in a `Query` as per #2592.

Will attach a totally trivial patch that does this, breaking no tests, and applies cleanly on rel_0_8, rel_0_9 and master.
