Fix confetti appearing in awardModal.

The confetti button in the awardModal had a conflicting ID to the
newly-reimplemented confetti award. This resulted in an amusing bug
where the awardModal was filled with confetti. Conflict has been
resolved by renaming the confetti overlay.

This is what I deserve for writing code at 3AM.
