- Made the exp bonus settings be adjustable:

- exp_bonus_attacker: Indicates how much additional exp a mob gives per additional attacker (eg: 10 -> +10%*attacker)
- exp_bonus_max_attacker: Indicates at which number of attackers the bonus is capped (eg: 5 -> 5 attackers, so a mob yield the same exp whether 5 or 10 people attack it)
- Changed the way the party_even_share_bonus setting works. It now uses a simple linear bonus increase (eg: 10 -> +10%*party member)
- The defaults are as explained by Tharis: +25%/attacker, capped at 12 attackers, no party bonus.
