- fix a bug in CopyHandler (while copying slot objects) - found and fixed two cases, where xotcl could crash during deletion of active objects - simplified deletion logic of active objects significantly unsing an explicit activation count - removed old deletion logic (state variable callIsDestroy, callstate XOTCL_CSC_CALL_IS_DESTROY, destroyedCmd on stack content) - removed now obsolete functions CallStackMarkDestroyed() and CallStackMarkUndestroyed() - made changes for with and without TCL85STACK
- defined new (3rd) frame type FRAME_IS_XOTCL_CMETHOD for calling c-implemented methods (the same as FRAME_IS_XOTCL_OBJECT, except that it uses csc as clientData instead of only the xotcl object - implemented XOTclCallStackFindLastInvocation() for tcl85stack
