Bug 880917 - Remove AutoVersionChecker. r=luke

Browse Source 
Looks like cdleary added this back in bug 595691, as an equivalence to some
even-older-and-more-overly-cautious XBL code that was saving and restoring
the version across XBL calls. It doesn't seem like this should be an issue
anymore, and it's just a debugging aid to boot. Let's kill it.
