Proposition for developers: new NPC special

[ChaosSlayer]

How about this small implementation?
Currently the game will not recgnize any spells with ID # greater than 10,000

This severely limits ability to make new spells, wihout deleting a whole bunch of old spells, which automaticly cuases problem for all NPC spell lists which based on old spells, and prevent doing customization step by step (I need rathly 350 spell ids per class just to begin with)

Could you please increase the size of the variable that holds spell ids up to say 20k?

Thanks =)
