Global save file not saved if you close program via ALT-F4

[drojf]

A user reported issues with their volume slider not matching the game state

While this did fix the issue: #117

I asked them to restart their game, and they said the volume reset to 100%

It turned out the user had been closing the game via ALT-F4, which causes the game to not save the global.dat file, containing the volume (and other things)

To fix this

• Save global.dat periodically (although it would be hard to know exactly when because there are so many files there)
• OR Hook ALT-F4 and do save when exiting via this method . But this won't prevent issues if the game crashes, for example.

May also want to check whether saving the global.dat is done in such a way it is not corrupted if the process is interrupted half-way.

Actually I tested this and it does save on ALT-F4, the report was me misreading the user's comment
