This hefty update includes all of the MCP (Morphic Cleanup Project) 
changes so far.  Diego has already checked for conflicts with the 
recent KCP changes, and separated the Test-related changes.

Thanks to the MCP and KCP teams for their great work!  From here on we 
can harvest all sorts of other enhancements and fixes.  (Of course, any 
Morphic-related enhancements/fixes will need to be checked for 
conflicts with these MCP changes, since there are a lot of them.)
