Added an image merge feature loosely based on a merge function found in
the open source project Wormux. To improve SDL performance, the number of layers that are pushed out to the hardware or software buffers should be reduced, which is where this function comes into play, as it combines two surfaces together so that the number of blit operations is reduced. This function is currently not used, but will be used once a good way to link each of the target systems is determined so that it only initiates when SDL is enabled, as well as making sure that each hook that uses this function is benefiting from it sufficiently. At the moment, it's suspected that the particle engine will likely be the most likely to benefit from this function, followed by tile drawing, then sprite drawing.
