Replace rebooter with timer and price increase#758

Being able to use a powerup only twice is a nusiance, especially in longer games. Therefore, I propose that the rebooter be abolished, and that most powerups are re-unlocked after a time limit, at an increased price for the first five reuses.
suggested time cooldowns to reuse powerups:
deflector: 5 minutes
icer: 2 minutes
blur: 1 minute 30 seconds
gift: 1 minute 45 seconds
music-changes: when two other players use a music change
clapinator: ONLY CAN BE USED ONCE

I would like to see tis actually considered, for us non-premium student users are seen as unworthy to make suggestions. Adding this powerup would revolutionize gimkit, especially for long games.
