Seems like we request a lot of IDSResources with id 0 (we should not).
Return "" instead of throwing an exception (for now)
Renamed the two IDSResource::ValueFor() to StringForID() and IDForString()
Fixed Object::IsDummy()
Added EnemyAllyValue
Pass "ENEM" for enemy id. Debug code change
Don't print the node
Compare strings case insensitively
Implement resolving identifier LASTATTACKEROF
