beta 1.6+1.7

1. After accidentally deleting my player I rebuilded it better than before.
2. I also reworked the mouse-wheel interaction system, so it is useable.
   
3. But you can't use the right-mousebutton anymore to interact, so the bug where you get stuck in the valve is also fixed.

There are still some bugs and I'm about to fix them but if you find anything please report it to me.

Thanks :)
