Line of Sight Visualizer: Init

This is a partial rewrite of https://rop.nl/freifunk/line-of-sight.php. Webscraping got replaced by API-Calls. The main functionality is working, however more detailed information cant be shown as long as there are not available as attributes in the wiki. I consider this optional as you can still get all the relevant information in the wikiarticle, so its not strictly needed in Google Earth. Since big parts of the code are legacy I excluded them from linting. Otherwise a way bigger rewrite would be needed. The code still works as expected.
