Marathon Run fixes (Resolves #184)

• Apply the RTA penalty to the live event backup rather than the current timer. (Resolves #184 (closed))
• Fix live event backups being created at run start; there's no meaningful progress in GFZ1 to recover from.
• Snap the character name and timer mode text to the bottom of the screen, just above the bar.
