sdl_mixer, sdl_ttf, and sdl_net do not uninstall fully

[KieranP]

I installed sdl_mixer. It got updated, I uninstalled and then reinstalled, but got an error:

% brew uninstall sdl_mixer

sdl_* use a symlink hack which installs files into the SDL folder, which IMO.

However, if it's the only way, two new things needs to be put in place:

1) sdl_* needs to make use of a before_uninstall method of some sort. While making that method, an after_uninstall wouldn't be a bad idea either.

2) The dependson system needs to make it so you can't delete say sdl without deleting the sdl* files first.

i.e.

Cannot uninstall SDL because sdl_net, sdl_ttf and sdl_image rely on it. Please uninstall these first.

This should make sure SDL doesn't get deleted, and mess with the files of those other packages.

Thoughts?

Totally agree that this is a hack (since I'm the one who did those formulas) but don't have a better suggestion at the moment.

Yeah I have ideas for fixing this hack. Will enact them soonish.
