* Added support for using a lookup table for creature mana / health

* As long as creature level, class, and the proper expansion they are from are
* set in creature_template, you will have 100% accurate health and mana.
* Research and base stats table done by Malcrom -- THANK YOU!
* Original patch by Kudlaty -- THANK YOU!
* Updated and enhanced by Machiavelli - THANK YOU!
* Optimizations by w12x, MrSmite, and XTZGZoReX -- THANK YOU!
* Final code updating for current rev by XTZGZoReX -- THANK YOU!
