Since Tiles.yaml is no longer empty, uncommenting this
Added Position.toString()
Replaced crossroads.png with lighter version

Because players names were invisible on previous image and I'm too lazy to think of other way of handling this.
Added getters for MovePlayer and added missing msgType
Added movePlayer() and initPlayersOnMap() to GUI

Second is a bit hackish, but I can't think of anything better at the moment.
Map is now clickable, added End Turn button
Nvm, that was stupid
Added a bit of working MovePlayer and PlaceTile logic
