The old system of cloud access updates with fake percentages just wasn't helpful. Even worse, it hid a lot important information from the user. This should be more useful (but it will require that we localize the messages sent from the git progress notifications and make them more 'user ready'). Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
