Usually something like __IRR_SOME_GUARD_INCLUDED__ replaced by IRR_SOME_GUARD_INCLUDED.
Removing underscores at the end wasn't necessary, but more symmetric (probably the reason they got added there as well).
While this touches every header it shouldn't affect users (I hope).
Also a few whitespace changes to unify whitespace usage a bit.
And a bunch of spelling fixes in comments.

setTexture functions for single textures (more or less the usual case) IRenderTarget no longer need memory allocations
on each call.
Also calling IRenderTarget::setTexture with a nullpointer no longer sets a rendertarget with an array which contains a single nullpointer but clears the array instead.

Still can't decide on fixing/leaving function names... brr
