Clean up all program close paths to use VVV_exit()

Wow, there are a lot of these. All of these exit paths now use
VVV_exit() instead, which attempts to save unlock.vvv and settings.vvv,
and also frees all resources so Valgrind is happy. This is a good thing,
because previously unlock.vvv/settings.vvv wouldn't be written to if we
decided to bail for a given reason.
