MySQL for Python: ZMySQLDA 3.0beta release

MySQL support for Python. MySQL versions 3.23-5.1; and Python versions 2.3-2.5 are supported. MySQLdb is the Python DB API-2.0 interface. _mysql is a low-level API similiar to the MySQL C API. ZMySQLDA is a Database Adapter for Zope2.

First and hopefully only beta release. It has gone through extensive testing already and is being used in production. Final release will occur once I've had a chance to beat on the Unicode support a bit more.
