Make use of GeoDjango

showelectricpanel template now makes use of leaflet instead of openlayers3, as
it turns out leaflet took 1h to setup and has a lot of documentation, while
openlayers3 took a while and I couldn't figure it out.

Now the page will show the current state of the lines and the location of the
panel when requested
