Thank you very much, Kinoc for:

* Impelements llInstantMessage
* Reimplements llOwnerSay as llInstantMessage(llGetOWner(),msg).
* Try's to better identify the "True Name" of objects in llDetectedName
 by checking for avatar name, scene Object Part name and entity name.
* Uses similar logic in the llSensor and llSensorRepeat functions.
