Add "Experience for hurting an enemy multiplied by the damage done and multiplied by the victim's level"

[Z-RAY-Z]

We have two settings in smrpg.cfg:
// Experience for hurting an enemy multiplied by the damage done
// Experience for a kill multiplied by the victim's level
What about add new setting:
"Experience for hurting an enemy multiplied by the damage done and multiplied by the victim's level"
This will help get experience for new players, even they can't kill strong players.
