started implementing battleground experience system

-players gain xp by killing enemy players (event bonuses not added for now)
-player can switch xp gain on/off by talking to npc Slahtz or Behsten for a fee of 10golds
NOTE: turning off xp gain will turn off ALL xp gains from quests,monsters,pvp,etc
