add unicode encoding for py2k for the non-native hstore, pullreq for

Fixed a regression from 0.7 caused by this ticket, which
made the check for recursion overflow in self-referential
eager joining too loose, missing a particular circumstance
where a subclass had lazy="joined" or "subquery" configured
and the load was a "with_polymorphic" against the base.

Fixes to the ``sqlalchemy.ext.serializer`` extension, including

Fully implemented the IS and IS NOT operators with
regards to the True/False constants. An expression like
``col.is_(True)`` will now render ``col IS true``
on the target platform, rather than converting the True/
False constant to an integer bound parameter.
This allows the ``is_()`` operator to work on MySQL when
given True/False constants.

The operators for the Postgresql ARRAY type supports
input types of sets, generators, etc. but only when a dimension
is specified for the ARRAY; otherwise, the dialect
needs to peek inside of "arr[0]" to guess how many
dimensions are in use. If this occurs with a non
list/tuple type, the error message is now informative
and directs to specify a dimension for the ARRAY.
