#2 Visibility vs. Jamming

[Turbo Beholder]

(tap.. tap... does this thing work?)

Right now, units with "jam_only_own_field" grey out the whole hex, which in part defeats the purpose.
If units had separate visibility and jamming adjustments, an unit would be truly hidden. Conversely, visibility could be greater than normal for certain terrains - mountain, lava? Same for huge objects and units - e.g. battleship, maybe shuttle (when not on orbit, which requires "Satellite View" anyway).
