- modernize test a little: all local definitions of proc "?" are gone. - added interface to test: "Test parameter count SOMEVALUE" to specify conveniently e.g. the number of tests the be executed - add XOTCL_CM_NO_UNKNOWN to dispatch of defaultmethod
- added option "arg=.." to parameter options; this argument can be passed to converter; used currently for "type=relation" to flag, that the relation type is different from the parameter name - extended "objectparameter" to handle such cases - removed relationtypes "mixin", "filter", "instfilter" and "instmixin" since not needed due to converterArg
