Added Licence exception for Pebble smart watch port of Super Gravitron

Just did my first SDL3 compile and noticed the console messages didn't
have any color anymore... Because that was conditional to
SDL_PLATFORM_UNI. I saw this during the SDL3 PR and found it odd, but
it's on https://wiki.libsdl.org/SDL3/README-migration#sdl_platformh.
It turns out it actually doesn't exist, it's supposed to be
SDL_PLATFORM_UNIX.
