Behaviour change: now gather console logs since launch, instead of 24 hours

Previously, if PLIST_KEY_LOGHOURS was not set, it gathered the last 24 hours of
console logs. This could be way too much, or too little, but was quite arbitrary.
Now, gather everything since the app started (this could be much less or much more).
