Move "getNPC" that was introduced in commit

00729bbc2e
from Spawn to CreatureType

I didn't have a closer look at how his code was structured, what he
basically did
is that he set all creatures in a spawn as NPC's even if it's a monster
which is
so erroneous.

Highlights:
- Add branch prediction macros
- Minor code style fixes & some others

Hopefully the branch prediction thing will speed up OTB since it's
awfully slow.
