[Tuxmath-devel] Patch: Cleaner exit on error

[David Y. <hob...@gm...>]

 Dave & All,

Thanks for the great program!

I just got a binary of a year old with Ubuntu, and wanted to slow things
down a bit for a less advanced kiddo. I downloaded the latest from svn, and
it was already there.

I noticed that if I am running fullscreen and exit due to a failure to load
images, the screen resolution stays at 640x480. It's easy enough to change
it back, but annoying.

So, I modified the exit on errors to cleanup a bit better. Now error exits
in setup.c call SDL_Quit and the other heap cleanup that was already present
on a normal exit. Except the first error exit because no heap space
allocation or SDL calls have been made at that point.

I made the assumption that if exiting due to an error, you wouldn't want to
save the options to the configuration file.
