* A bit of spice from here, a pinch of salt from there, some brains that attracts zombies.. a recipe for llRezObject

* Original patch by YZh Thanks YZH!!!!
* object_rez event patch by Melanie, Thanks Melanie!!!
* Some fixups, some missing things(velocity,rotation)
* script delay
* Recoil
* Standard error messages
* Standard silent failures
* Easter egg management
