Implement a 32bpp SSE2 palette animator. This is ~4x faster than 32bpp-anim's.

Browse Source 
Create a new blitter mode: 32bpp-sse2-anim, which is 32bpp-anim + this.
32bpp-sse2-anim is now used by default where 32bpp-anim would have been.
Also use this with the 32bpp-sse4-anim blitter mode.

Fix memory leak in current 32bpp animated blitters.
