#106 Inheritance issue(s) with proxied data objects

[Matt Tierney]

Refer to the unit tests that are failing in the net.sf.dozer.functional_tests.proxied package. It appears some mapping defs are being lost and is specified to CGLIB(or other) proxied data objects. I think checkForSuperTypeMappings() may contain the problem and is a good place to start.

I fixed one of the issues in ClassMapFinder, but there are still failures

I applied some more fixes. 85% of failures have been resolved. I am guessing that the remaining ones will be tricky

Required refactoring to existing inheritance logic. Doc's need to be updated to account for changes in inheritance behavior.

**NOTE** Folks using inheritance mappings will need to regression test thoroughly after upgrading to 4.1
