Many problems persist with reliability of autobackup in some games.
OnRename has a recursive call if IOException is an IN USE exception. Currently recurs once, but Skyrim saves
SBTErrorLogger.Log now takes a string parameter instead of just an exception. Allows me to add info to the string in catch statemetns.
After 10 recursive calls, SaveCreated would exit and many other events would not occur. Removed recursion limit, at least temporarily, with the aim that the timers should avoid large recursion counts
Skyrim save and quicksave are currently working.

Quicksave debug text is somewhat confusing until I realized that autobackup was attempting to mimic the Skyrim operation that keeps three quicksave.ess.bak backup files at a time.
