Human Factor - New controllers / attached camera

I have now changed the controllers on the client so that the scrollbar will not be available as a input device. This change was done to better simulate the real life, as you would not be able to move the crane faster than the engine would allow you to.

I've also added support for attaching the camera to an object. This can be seen in the second screenshot, where I've attached the camera just above the crane looking down. You can also see that Torbjørn has had time to add textures to the models. The world has never looked this good before.
