Frage Animal script version 5.7 - YEngine support

A new animal rezzer/updater is now available.   This has various fixes and updates and has been tested on the current official release of opensim (0.9.2.0) under the new default YEngine. Please note that earlier versions of the animal script will not work under YEngine so you should update any existing animals under XEngine before you switch.
