2014.12.10 MSS Code Factory 2.0.12692 Restore Java Sybase custom tags for 2.0 models

The Sybase support is being restored by 2.0 for the 2.1 projects, because I
remembered how to deal with the mutable complex join issue in Sybase ASE.  The rules
will get forward ported from 2.0 to 2.1 after testing is done with that implementation;
I've been trying to keep the code bases for the engine itself in sync manually.  I think
the rules probably still need a bit more work before I'll have clean 2.1 code again
for Sybase ASE.
