Devices are shown on the map as "routeronly":

This is an issue of hopglass. There is a python script, which checks for this property. This also relates to the migration-issue. Currently Falter does not communicate itself as freifunk firmware, but as OpenWrt. Hence the wrong properties at the map, because that script only bothers for "freifunk"-firmwares.

This should be solved by freifunk-berlin/hopglass.berlin.freifunk.net#13

As quickfix, in this PR we derive the hotspot-property from having uplink. After we have made the owm.lua privacy friendly, we cannot for sure say, if a router has it's wifi disabled. Before, we looked up that stuff in the complete list of interfaces.
The solution of #159 might solve that as well.
