Added site marker (and settings for that)
Shows radars location on map. Default is not showing.

Settings:
SiteShow is boolean [true|false]
SiteLat & SiteLon in decimal format.

If using untrackedDeveloperSettings.js-file these settings can be
copy-pasted on that file:

SiteShow    = false;
SiteLat     = 45.0;
SiteLon     = 9.0;
