Minor main menu changes.

- Changed the time format displayed on the main menu to match osu!.
- If no beatmaps are loaded, redirect the user to the downloads menu instead of an empty song menu.

Also, start showing bar notifications at time 1 instead of 0 so it can be called in enter() methods without visual delays.
