Adding basic cameras information when hovered on map

[VincGargasson]

This PR change a bit the function to grab the info when hovering the mouse over the map. If the user hover over :

• a department, it shows on the right box on the top the name of the department
• a camera marker, it shows on the right box on the top basic information about the camera

A second commit should include popup when clicking on marker.

Mmmh, could you merge master into your branch @VincGargasson please? There seems to be some conflicts and for reasons I don't exactly get, the CI did not trigger :thinking:

I see there are just 2 minor issues with codacy (related to docstrings), it should only take a few seconds ;)

[VincGargasson]

@frgfm @pechouc @nrslt Need your help. Codacy drives me crazy ! It state blank line required between summary line and description in app/utils.py while they asked me just before to start the description at the first line.

Any of you has an hint of what's going on? :) Thanks

I had the same issue with a previous PR, Codacy is trying to verify two styling rules that are not compatible. The only thing to do is to ignore the remaining comments, since Codacy is not blocking the merge anyway!

[frgfm]

@VincGargasson yes exactly, it's not blocking because it goes a bit nuts on small things like this. Don't mind them!
