SHOW - allow infinite looping of sequences

[theeldestelder]

Allow a sequences to be played infinitely. This is useful at places like Spring Jam where one sequence runs forever.

Error was found that after 30 minutes the player will slow down with this submission b6b23ad

The slowing down doesn't just happen all at once. It's just around then that it's super obvious that the sequence is slower. It is also noticeable before then. Just less so. I'm not sure if repeating the shows is causing them to stack up or the timers we're using aren't accurate enough which only becomes noticeable after a while or what.
