- commented out XOTCL_CMD_NOT_FOUND, since it seems to be obsolete by now - extended regression test to avoid CallDirectly on dealloc (the last place, where XOTCL_CMD_NOT_FOUND was used)
- made the "next scripting laguage" a own, loadable tcl package (currently named nx, name is subject of change) - predefined.tcl is now pretty minimal.
