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