Fixed new compiler warnings in test code.
Added test for toll-free bridged objects. They would lead to recursive CFRelease calls in the current isa-swizzling implementation. Don't know how to test for that with a decent fail, though.
Fixed toll-free bridged object test: Not permitting stubbing of toll-free bridged objects for now.
Fixed UIKit.framework project reference to be SDK relative.
Added test case for objects that override isEqual: and hash. It's not possible to stub equal but not identical objects due to bad test in stubbedObjects set.
Fixed isEqual issue for stubbed objects.
