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).
Revert "Behaviour change: now gather console logs since launch, instead of 24 hours"

This reverts commit d15b3fbc1941eb845c9da2b06ba050bfa9e75503.

It wasn't a good change because if checking for crashes at launch,
the process has only been alive a few seconds and you want older
console information than that.
Fixed spelling typo in comment
NSLog some unicode in applicationDidFinishLaunching in test app

Always having this text in the console logs ensures unicode doesn't get broken.
Always use ISO 8601 date format in console logs.

- changed console log gathering to always use ISO 8601 date format "yyyy-MM-dd HH:mm:ss".
Previously the user's format was used, which made automatic processing harder.
- replaced deprecated atof() with strtod()
