This is my first attempt at modifying the code, so please go easy on me.

This is just a bit of code to allow admins to modify the amount of EXP earned, AAEXP earned, and the EXP bonus for each additional member of the group. If this is something people want, I'd like to expand it to include Quest EXP vs. Mob EXP, death penalties, mob stats and other balancing issues as well. All of these would be controlled through table entries so that admins could make some balance changes without deciphering the source and recompiling.

The current entries are all controlled through the variables table

• GroupEXPBonus = EXP modifier for each member of group (default = .1)
  
  EXPMod = EXP earned multiplier in GetEXP (default = 1.0)
  
  AAXPMod = AAXP earned multiplier in GetEXP (default = 1.0)

Anyway here's a diff against the zone directory vs 0.4.4-DR1.

I'm not much of a C++ programmer, and do development on Linux so I'm not making any promises. Any feedback or other project ideas are welcome.
