Make Deploy progress more GUI

Here's typical output in the console from a deploy to app engine standard. About half of this is irrelevant to inaccurate for someone deploying in an IDE. Instead we should pop up a progress dialog, and ignore the lines like "add --promote if you also want to make this service available from" that don't apply to us.
