2014.10.19 MSS Code Factory 1.11.12492 Remove last vestiges of [get|set]OptionalLookupSuper usage

The custom code no longer relies on the old 1.6 get/set of the Optional Lookup Superclass Table
attribute of a Table object.  There were only a couple of vestigial cases of that code left.
It *does* work because I maintain that linkage during the parse and merge processes, but it's
not the way things *should* be done so I tidied it up.  It might slow down processing a tad,
but it's *correct* this way.  And for 2.0, the vestigial table reference will be removed, so
it'll be easier to port this code than what had been used.
