Reworking IRenderTarget interface to avoid constant memory allocations.

Browse Source 
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.
