UX: Automatically check for updates and start on successful update checkbox

[Beherith]

It takes 3 clicks, with quite some time delay between them to get into the lobby, and I would be very pleasant if there were a checkbox on launcher (probably used by most players) that stated:
[x] Auto update and start

And if a user enables it, then the launcher will start the update checking once launched and the starting of the lobby once the update succeeds.

Thank you!
