Closing multiple instances of the game at the same time might break settings.vvv

[Daaaav]

Might need further investigation, but if you close multiple instances of the game with an option like "close all windows", then the following might happen:

[ERROR] Error parsing existing unlock.vvv: Error=XML_ERROR_EMPTY_DOCUMENT ErrorID=13 (0xd) Line number=0
[INFO] Creating new unlock.vvv

It seemed like the settings that were also in unlock.vvv were fine, but things that were only in settings.vvv were not (like time trial centiseconds) so I just restored them from a recent backup.
