- 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
- removed all unreferenced entries from XOTE_* - regrouped XOTE_* for easier comprehension - used XOTE_* on more occations - used XOTclCallCommand() for calling Tcl "format" and "interp"
