Powerups, map display and more!

Patch notes:

• Picture of the map when you choose. It shows up when you select it - Powerups - When they’re taken, they should disappear until you can pick them up again - On your screen it’ll show you what powerup you have and how long you have left - Updated timer and ‘it’ text to be the right font - Fixed issue with multiple people being ‘it’ in the Normal Tag game - People who are ‘it’ can now get the powerups

We experimented a lot with the powerups and we think these changes will make the game much more fun, especially the 'it' people being able to grab the powerups now!
