Prototype: Interactive SVG map

[GDur]

Hello

This fork will make the SVG map interactive. This means the destination AstroBody circles and labeles are clickable.
As a hint, the "from" and "to" Dropdown menus have been removed visually.

The code is only a prototype/proof of concept, so it is not bullet proof atm.

Let's first see if this is a feature which other users find as desirable as I do. :)

Thank you for reviewing this fork.

Thank you for your work, I think it can be a promising idea.
I will look into your PR when I find the time.

Thank you for your great contribution. Starting from your code I created a version where we can select a destination with landing or not:

• I made only the 'ground' and 'low-orbit' elements clickable to correspond to the path in the panel selection
  
• The 'landing' checkbox is automatically checked or not following mouse selection
• I kept the right panel selection, I prefer this way for now, especially since the mobile version shows only the panel, and not the map
