Ground track improvements #194

Open srcejon opened 4 years ago

This patch add arrows to the ground track to show direction satellite is moving in, as requested in Issue #94.

I've also added support for automatically enabling the ground track for a satellite when it is selected. The ground track is then cleared when selecting another satellite or deselecting the satellite, unless the ground track was enabled manually via the menu.

I've added an option to the GUI (key=AUTO_GROUND_TRACK) that controls whether this feature is enabled or not, to allow users to keep the old behaviour.
