* Patch from Mic Bowman(cmickeyb) that implements llUnsit. Thanks Mic!

* I expanded upon his patch just a bit to incorporate the following.
* if the avatar is sitting on this object, then we can unsit them.
* If the object owner also owns the parcel or if the land is group owned and the object is group owned by the same group or if the object is owned by a person with estate access, then we can unsit them.
