Move RM 2.2 dependency to 4.2.2-SNAPSHOT

 * fix issues so that RM 2.2 is still backwards compatible with 4.2.1 (and 4.2.0)
 * added 'bean extender' .. a post processor bean that allows us to extend, rather than overrite, core bean definitions.  Gives us a technique we can use that won't be disrupted when changes are made to core bean definitions.
 * unit test for above
 * tested with 4.2.2-SNAPSHOT and 4.2.1
