Subject: [PATCH] Add JsonRezAtRoot script function. Operation is very similar
 to llRezAtRoot except that the start parameter is a Json string that will be
 unpacked into a json store identified by the objects uuid.  This makes a much
 more expressive (and simpler) way of passing initial parameters to a rezzed
 object.
