Show the cheapest gas station on the map

[riker09]

I use the Tankerkoenig intergration and while it works I think there is room for improvement.

I'm using the integration to monitor gas prices of some gas stations nearby. I want to see the stations on the map with their brand logo and when hovering over the icon the current gas prices should pop up.

In my dashboard there should be a tabular view with the cheapest station on top. I could image that there is even some room for a link that opens up my favourite routing app when viewing the dashboard on my smartphone.
