Muter tells the user when there's a new version available at the start of a run

If this is implemented, it would be great to have an option to disable it; running muter on a plane or somewhere similar with bad wi-fi and having to wait for a version check would be aggravating.

The version check could happen asynchronously, and alert the user at the end of the run if it returned, so it wouldn't be blocking. I suspect fastlane does something similar, just based on when it prints. It should still be disable-able with a flag, though.
