SaVi satellite constellation visualizer savi-dev

Updates to packaging procedure.

Altering the cosmetic sunlight hack to inherit from smiulation
constants, as it always should have done.

Improving params handing. params(orbital_period) is time around the Sun.
we create a temporary variable to deal with rotation of a day.

Making Clarke geostationary follow the current stationary
radius set by body parameters.

Tweaking simulation parameters to show period
(sidereal day) rather than less clear radians/second.

We could do a similar thing separating out the G and M
of Mu, but entering the mass of a planet is painful.

Improving stationary altitude calculaton to work off simulation constants.
Tcl's floating point is a pain. We use the old pow(x,y) form.

Minor about tweaks.

Updating copyrights for year.

Updating manual for changed projection list.

Only loading optional maps in if -all-maps flag is given.
