Allow single-block groups full functionality on toolbars (esp. cameras)
Currently, many blocks bound to toolbars are erased after being destroyed, even if they are replaced via projector. This can be circumvented in many cases by placing a single block (such as a timer block or a camera) in its own group, and putting the group on the toolbar.
Unfortunately, in the case of the camera, this prevents the "View" option from bring bound. This makes sense for multiple cameras in one group... but not-so-much for a group consisting of only one camera. I believe the same is true for the Jump Drive block, even when there is only one drive in the group.
One should be able to bind all possible functions to a toolbar when the group consists of only one block. Players waste a lot of time constantly re-binding blocks.
