This commit addresses multiple issues with the CCDD patch handler. Wh…

…en the patch is applied to a CCDDv1 database all of the arguments in the 'Command' table type are removed and placed in a newly created table type called 'Structure: Cmd Arg x'. During this process many of the non-required fields like the 'Description' field were being cleared, non-required table type columns were being flagged as required, too many unnecessary/duplicated table types were being created and too many data columns were being added to the newly created table type. This commit also addresses a naming issue that was occuring during the patch.
