- removed methods object-mixin and object-filter from the interface. (Caused some duplication of logic in the method "object") _ added option noforwarder to RelationSlots - some minor cleanup
- renamed "info method name ..." into "info method handle ...", since it returned already the handle - renamed ListMethodName() to ListMethodHandle() - changed output of "info callable -which ..." from definition to method handle - renamed "info callable -which ..." into "info callable method ..." - updated regression test to reflect the changes
