Title: DB abstraction layer modified

Lock and Unlock table introduced at JDatabase class
DropTable, Show Tables and Rename tables introduced JDatabase layer and implemented in drivers.

The above two are mandatory to make Joomla support other databases.

Some files were modified to support JDate->format rather than mysql specific ones.

Please let me know if you have any questions/concerns and will be glad to assist in any way I can.
