gfx_surfaceDestroy_SW didn't actually free the Surface! Also changed surfaceDestroy and paletteDestroy interface

So memory was leaked when you imported a 24/32 bit BMP.

These functions now take a ptr ptr as argument and zero out your pointer
even if the object isn't actually freed, to avoid bugs, just like
frame_unload and palette16_unload.
