- Created a new Screen called Play.java as the main screen for the game
- Modified the DarkParts.java to stop showing the LibGDX logo and show
our game instead
- added mapa.tmx and test_tileset.png as the testing map

(Fukken Hell, we actually managed to load the map, do you get it Saša?
I can hear the sound of progress already, my friend. :D This is the
farthest we got to creating a game with graphics ever.)
