#2 Add MySQL interface

[Jerry Seutter]

Stuff changed:

Added MySQLInterface.java file - Added MySQL database
support.

Modified DatabaseInterface.java - Modified the save()
methods to allow Search parameters to be supplied for
an update statement. You probably want to review this
file before adding it to the source tree. I have a
feeling I didn't understand this interface correctly.

Modified PersistentFactory.java - Added a
storePersistent() method to the interface.

Modified Search.java - Fixed a bug where stuff was
getting double-quoted. At least I hope I was fixing
something. :) You'll probably want to take a look at
it as well.

Patch by doing the following:
cd dbixx/java/dbixx
patch -p1 < mysqladd.diff
