Ability System almost completed

* Award Ability, revamped this completely, it is now almost fully
functional, it SHOULD work for aquirement of ability from neutrals but
it needs testing first.
- A bunch of old functions not used anymore
+ Ability Table - Index Of Ability
+ Implementation of global static "Ability Table" for conversions
inbetween "unit type(item)" abilities, custom value abilities and unit
data abilities.
