SaVi satellite constellation visualizer savi-dev

Fixing save and load of satellites as Tcl script so that names match
their satellites. To do this we throw away some information from GET.

Making url tle loading more robust.

Noting demise of LeoSat.

-ansi is now evil, as under recent gcc it interacts with
non-posix file redirection to break Geomview interaction.
So, we remove even commented mentions of it, and we will

already implemented in most scripts.

Why we're not simulating 42,000 satellites...

noting launch flag in string for about 'obeyed' section.
Whether -verbose is only obeyed if running -geomview or -fake-geomview
or is not included if they're not run -- or whether it also specifies
a more verbose debug -- is still up for debate.

Updating with note on chmod for file permissions.

Noting geomview/-fake-geomview flag interaction.

Noting the -verbose command flag.
