MySQL for Python MySQLdb-SVN

Python Sets (from sets module) as parameters work, but *only* Set
and not ImmutableSet. Still trying to get it to work on BaseSet
so any subclasses will work.

Fix client_flag fubar and add support for more detailed warning
information available from MySQL-4.1 and newer server.

Add sets module support and make boolean support non-optional

Remove sets module in favor of standard sets module (Python-2.3 and
newer)

Remove FIELD_TYPE.CHAR (deprecated) from STRING set since it conflicts
with FIELD_TYPE.TINY (NUMBER).

Fix fubared TimeDelta_or_None and Time_or_None

Remove erroneous insert_id() on cursor reference.

Translate some additional error codes

Documentation is good. Correct documentation is better.

Enable MULTI_STATEMENTS if the client library is 4.1 or newer.

Enable MULTI_RESULTS if the client library is 5.0 or newer.
