GTK: stop referring to &thegame in prefs I/O functions.

I had to do this in the Windows front end to cope with compiling in
both COMBINED and one-puzzle mode: you can't refer to &thegame because
it might not exist in this build, so instead, if you want to load/save
preferences for a given midend, you ask that midend for _its_ game
structure, and use that to make the necessary file names.

On Unix, we don't have COMBINED mode. But now I've thought of it, this
seems like a good idiom anyway, for the sake of futureproofing against
the day someone decides to implement combined mode on Unix.

delete_prefs() doesn't get passed a frontend _or_ a midend, so that
just has to take a bare 'const game *' parameter, and in main() we
pass &thegame to it. So that will still need changing in a combined
mode, if one is ever added.
