Void type change 2

I'd like to re-regsiter Void as a normal/shadow type, since he's a shadow person, and it shadow is closer to the original wind type that was around when I first made him. The summon type was more of just a fun idea that I've wanted to try, but the shadow subtype makes more sense IC and for my style of combat...

old sub type: normal/summon
new sub type: normal/shadow
