New Mapflag adjust_skill_damage

Made as a improvement of the original ADJUST_SKILL_DAMAGE -- special thanks to Muad_Dib! .
This mapflag allows you to modify the damage of any skill in any map, for example
"prontera	mapflag	adjust_skill_damage	MG_FIREBOLT	200"
doubles the damage of Firebolt in prontera
Another Example:
"prontera	mapflag	adjust_skill_damage	MG_FIREBOLT	50"
Halves the damage of Firebolt in prontera.
