Changed properties.

Leaflet's default thing was just to post what was inside
of a certain properties json thing, but now instead, the
file nodes.go creates more properties to be shown in the
popup on the map
Changed the map width and added a modal.

The tools modal did not exist, it was just
half-made, so I finished making it. Also,
I made the map a much nicer 1000px instead
of a tiny 600px~
