(svn r24993) -Fix: [SDL] Improve 8bpp hardware palette support. Instead of always requesting SDL_HWPALETTE, it is now only done for 8bp blitters in fullscreen mode.

  - This fixes 32bpp blitters on 8bpp X11, which would only render garbage with SDL_HWPALETTE.
  - This prevents the colors of other applications from being messed up when running a 8bpp blitter on a 8bpp system.
  - When running a 8bpp blitter on an 8bpp system without SDL_HWPALETTE (e.g., in windowed mode), this uses a new shadow surface with color approximation.
  - The use of a hardware palette can be forced on and off using -v sdl:hw_palette=1 or -v sdl:hw_palette=0
