MySQL for Python MySQLdb-SVN

A few tweaks to the notes in preparation for the release.

Changelog and version number changes in preparation for 3.0rc1 release.

Applied patch from bug 2024618 by Federico Schwindt.

Added basic support for procedure calls using "CALL" query.

Removed deprecated (and unnecessary) methods line.

Corrected MySQLdb version dependency (set to 1.2.1).
Added support for NEWDECIMAL field type.

Made some changes to how use_unicode and auto_create_db are set to better allow
for subclassing and extensions of the base classes.

Added condition to handle connection getting "out of sync". This can occur
when, for instance, you get a stray semicolon in a query. When a connection
gets in this state it is hosed and must be closed and reconnected.

So in this case we do a close/reconnect as well as log a error about it.

Bug 1932309

Updated ImageFile to import from App.ImageFile instead of ImageFile as the
latter is deprecated and causes namespace conflicts with PIL.
