2014.10.23 MSS Code Factory 1.11.12501 Added container latch/unlatch code for Chained objects

Objects which define a Chain now latch and unlatch their container object by incrementing
and decrementing the revision of the container's base table prior to performing the
body of the sp_create() or sp_delete() functionality.  This has only been manufactured and
tested for PostgreSQL and DB/2 LUW; the other databases have been blind-coded.  As I've mentioned
before, you should stick with SP4 or 1.11.12499 until further notice.

Note that even for models incorporating Chains, this release is "safe" because all it does
is pin the container of an object before a Create or Delete operation in preparation for
manipulating the Chain reference links.
