New Prayer Feature: Plea

[AlexRose]

I'll discuss this idea in depth later, but perhaps the recently relased Extreme Prayer Potions could heal 100 or so PP? And the tithe should be based on prayer levels; the more prayer levels you have, the less the tithe is. Or, the PP expendure could be a function of your prayer level, so you would use less PP the higher your prayer level is (same effect, different way). There should, however, still be a set prayer level limit on each of the respective pleas.
