Subject:  add initial test support for cap LSLSyntax. This does not seem to
 work for Opensimulator on viewers, In particular with FireStorm seems
 impossible to replace its own definitions, viwers do note revert to defaults
 on tp to a region that does not suport this cap, etc. So possible just a dead
 end. Disabled by default
