- support for all string constraints provided by "string is ... $value" in object and method parameters ("alum", "alpha", ..., "xdigit"). Technically, these types are tclobjs (using converter convertToTclobj) having pParm->converterArg set to the constraints. - extended regression test
- refactor Slot class hierarchie - new methods in ObjectParameterSlot "toParameterSyntax" and "createFromParameterSyntax" - some more cleanup - removed legacy syntax for "-parmeters"
