Subject: XPM patch to SDL_image

A couple of people have requested an interface to SDL_image for loading
SDL images directly from #included XPM files in the C source.
Writing a separate loader for this would be silly as the code in SDL_image
already does the XPM parsing, so I added a new call to the SDL_image API:

SDL_Surface *IMG_ReadXPMFromArray(char **xpm);

which does the obvious thing. As a bonus, the code got a little cleaner as
well. (We probably need to increase the minor .so-version number since the
interface got changed but I didn't do so in my patch.)

We should perhaps include the rgb.txt colour name database as well, since
it's quite small (~13K in binary form), but I haven't made up my mind

Cheers,

Mattias
