Beta Potions 2.0

Beta potions only work during a frenzy or if the server is in beta mode.

To enable the server in beta mode:
- send o 0 FlipOnBeta
- Must also change the flag pbHiddenSwitch in Parliament class to enable beta mode fully. (Not sure why it was done like this, just matching the existing code).

Features:
- Allow players to select schools of their choice. Based on the
Intellect.
- Player will receive robes and reagents based on their selections.
- HP boost given based on stamina.
- Give maximum Mana boost based on Mana nodes found throughout the land.
- Several flags have been added to customize potions.
- String search has been adjusted for the lazy; so saying "qor6" will give you its spells. Don't have to say the exact phrase "qor level six".

Misc:
- DistributeBetaPotions message has been removed. Use the command send o 0 GlobalGive classtype class BetaPotion as a replacement.
- These changes have been heavily tested on a live server.
