- drop XOTclOSetvaluesMethod(), use alias for "set" instead of it - implement parameter option "optional" for positional parameters - extend regression test
- shortend some function/type names (e.g. use everywhere "Param" instead of "Parameter") - delayed parseContextRelease() in InvokeProc() until end if proc - process all argumens of proc/instpoc; before, this happend only, when nonpos parameters were used; - use parameter definitions only when they provide a value-add - finish freeing of parameter definitions
