- added argument for converter to return the converted tcl_obj, which should be passed on (currently only used for viaCmd); this way, we could remove the kludge of querying the converter after the conversion for special handling.
- new cmd "::xotcl::valuecheck <valueConstraints> <value>" where "valueConstraints" is whatever is allowed in e.g. parameters (including user defined types) - new Tcl_ObjType "xotclParam"
