I have found another way to create an app with the Mail API permissions enabled. I noticed if you include an 'api' parameter in the URL you can specify which scopes you want to include regardless of whether they are checked at the bottom. I noticed if you provided 'api=mail' in the URL it defaults to include Mail permissions. So to create a new app with Mail permissions use this URL:
