Add the ability to switch tournaments to the SetupScreen

[MiraiSubject]

This adds an extra entry to the setup screen that allows the user to switch the tournaments in the client instead of using the tournament.ini.

Currently requires a restart to apply the changes.

If it requires a restart, please trigger the restart.

Generally this will probably require UX considerations as to what happens if you choose another tournament. Getting booted from the game outright probably won't be the best option.

Yeah I agree. I'll be looking into something that will at worst reload the scenes to refresh the videos. Reading the bracket on switch seems a bit more complicated than I had anticipated.

For now I have addressed the review comments

At very least this should have a temporary exit procedure (even if it doesn't automatically restart the game). You can probably check how SquirrelUpdateManager does things and copy where applicable.

I got the panel so far changed so it now also contains a close button and it uses GracefullyExit() that's being used in the UpdateManager. I moved that to OsuGameBase so the tournament game can also use it.

As for restarting, I'm not quite sure how to go about that.

I tried adding the BindValueChanged of the Current bindable to the component creation and add the button once it changes. But I realised it already counts as a change when it gets populated initially. A solution would be to check if the old value is the same as the new value and then hide accordingly, but there might be a better way that I'm not aware of.

Should do for now.
