v0.2.0

Picked up this game again after like 8 months. Added some new features.

- Added new obstacles in maps: 
     - Portals
     - Moving saw-blades
     - Lasers
- Added a 'King' feature: When playing with 3 or more players, the player with the most points will wear a crown. When this player dies, the current chaser will get extra points.
- Added controller support
- Added and changed the maps: there are now 15 maps in the game, up from 5 originally.
- Added extra effects teleporting and spawning players.
- Players now have an 'ability':
     - Chasers can place 1 saw-blade per round
     - Runners can taunt. It does nothing. It's kinda funny tho.

And  some other changes that I forgot.
With controller support being finally in the game, I no longer have to collect 4 keyboards to play the game with.
