Make sdl's VID_SetPalette only queue a palette change.

Browse source 
It seems that SDL_SetColors causes a page flip, so VID_SetPalette only
queue a palette change (by checking for the need to change and storing the
requested palete) and VID_Update now checks for a queued palette change and
updates SDL's palette if required. This fixes the flickering console in sw
-sdl introduced by the cshift/centerprint change.
