Mars, baby!

Adding a popup planet selector to the Simulation constants dialog.
Currently, only choices are the default Earth, and Mars.

Proof that Mars works is that the clarke geo script computes 20427.68 km
as the stationary orbit radius, which is correct.

Still to do: forcing Mars color shades, turning off Earth maps (inc.
land/sea), even adding Mars maps.

Other planets/bodies could be added - Venus rotating backwards is tricky,
not sure about the Moon's gravitational model.
