Camera roll and mouse gesture

At least the camera control is almost finished: now you can pitch, yaw and roll, so you can do almost all movement into space.
So i've started to work to the mouse gesture: i've a GUI, and now is time to create some interaction between the mouse and the 3d world.
In this video you can see the ineractions between pointer and mesh.. when you left click in any mesh, its bounding box is displayed. Notice: when two mesh are aligned (i.e. the station and the planet) when you click on both, the engine selects the nearest.
