Added a non-random level

Added a "designed" level made through the editor. Removed the
GridManagerExample which contained the random stuff. Moved my testing
versions to a separate folder called "Kalle Tests" to avoid fucking
something up..
Made a Player and LevelInfo to store score n stuff.

Two separate objects are now used by the hud. The player object contains
score and name while the level info only contains the floor number.
