Added test background music

Just some static background music, started working towards #17
Upgraded to Unity 4.1.4f
Added direcitonal view and first decoration

Added a decoration shoing the way the player is headed to the GUD, as
well as a second decoration (roughly based on speed)
Started implementing Dummy GUI

for weight, direction etc. But It's all disabled.
Refactored input

Now the input is not directly linked to the player, but the
playercontrolelr initializes the Input through a InputManager. The
InputManger can handle remote and local input, and is the only public
interface for controllign a player. This also closes #40

Conflicts:
