/*
 This userscript will overlay a countdown timer on powerups, boosts, and bombs to let you know when they will respawn. 
 
 Due to a limitation in tagpro (to prevent cheating), the system cannot accuractly countdown items that were grabbed more than 10-16 tiles away from the player.
  		These items appear in red. RED NUMBERS ARE INNACURATE AND ARE ONLY AN ESTIMATE. 
    
    Color codes
        Number:
            Black: Guaranteed to be accurate
            Red: Innacurate, but probably will reappear before the counter hits 0
            
        Circles:
            White: Powerup
            Yellow: Neutral boost
            Red: Red boost
            Blue: Blue boost
            Black: Bomb
        
        
        
Before someone calls me out on it: This code could have been made slightly more concise/efficient... too bad! Time is valuable, efficiency here is less so. :P
