initial support for JSONB - this only allows you to define the JSONB
datatype - this does not add any of the additional support for
querying/indexing yet.
and tests for JSONB - as this is a superset of JSON i've subclassed
the JSON tests as all of these should be applicable as well.
add has_key & contains operators for jsonb (ported over from hstore)
minor cleanup of the jsonb - had extraneous operators that where copied
from hstore that don't apply.

Add tests for ? and @> operators.
it's OK to pass a dict in - it does the right thing, no need to quote it
in the tests.
jsonb support for <@, ?| and ?& added.

need to see if equality already works.

pg8000 passing test/sql
- The "evaulator" for query.update()/delete() won't work with multi-table
updates, and needs to be set to `synchronize_session=False` or
`synchronize_session='fetch'`; this now raises an exception, with a
message to change the synchronize setting.  This will be only a warning
in 0.9.7.  fixes #3117
-do an autoflake8 here
- Fixed bug where "python setup.py test" wasn't calling into
distutils appropriately, and errors would be emitted at the end
of the test suite.
- add 0.9 changelog
- Changed the default value of "raise_on_warnings" to False for
MySQLconnector.  This was set at True for some reason.  The "buffered"
flag unfortunately must stay at True as MySQLconnector does not allow
a cursor to be closed unless all results are fully fetched. fixes #2515
- lots of MySQL tests seemed to not be hitting all backends, so we should
be getting some mysqlconnector failures now
