Feature Request: Display world coordinates of crosshair next to voxel coordinates

[gdevenyi]

Right now, if I want world coordinates, I have to keep my mouse in a single position and read them off, it would be really helpful if the world coordinates of the crosshairs (which are fixed unless I click) were displayed alongside the voxel coordinates under the slice views.

I agree. They are in displayed in the menu window, but that isn't terribly intuitive or useful.

Just had a collaborator have some unexpected issues with coordinate confusion, probably due to this.

@gdevenyi Just checked this in. Let me know if it looks ok.

Glorious! Looks great!
