- added expermimental code to avoid "variable :x" crash based on shadowCommands, but this does not work, when varible is bytecompiled. deactivated for now.
- used Tcl_ObjCmdProc in prototypes - allow CMETHOD to be target of calling-object/calling-level - added NSF_CSC_CALL_IS_TRANSPARENT to handle proc aliases transparently - access self in NsfProcAliasMethod() from tcl->object
