[Foldit] Two small fixes for Foldit
Two issues noticed by players:
* Remove extra linebreak in log file for tool completion.
* If the debug.txt crash file is corrupted for some reason, it will stick around and never get deleted, shadowing any new crashes. Catch that situation and move the corrupted debug.txt out of the way. But if there's a server issue, keep it in the same location for a potential retry.
