Notes:
- The sRGB patch is now a simple text-replacement, as diff/patch files
seem to just fail. Even Homebrew's emacs formula does it this way.
- Removed fullscreen patch, as Emacs 24.4 includes fullscreen support on
OS X, both native and pre-Lion style fullscreen. More details here:

This also applies some kind of convention for the available options.
`--srgb` is still defined for backwards compatibility, but it technically
does nothing.
