Add big space support

[kolligs-nwp]

If you are working with grid cells from the big_space plugin to avoid jittering on geometries with large translation values, you need to add an AppGridCell resource to the meshes. If you don't do this, the mesh (or in this case the gizmo) will become invisible when the camera is on a different grid than the mesh.
This can be easily achieved by using an orthographic camera setting.
