Flush log data before process exit

In short lived processes Timber will not deliver log data because it maintains a buffer and flushes on an interval. Timber should flush the buffer before the process exits.

Thanks @eyefodder, a work around for now is to add a 2 second sleep before the process exits, but we'll get this resolved so that isn't necessary.
