Reorganize the layout

[n0skill]

It would be nice to have a better view of the different fields in order to have more information density. I propose having some kind of tiles.

Sure, we could have custom per hackerspace tiles, or globally for all the hs.. Then you'd have a "Add tile" button let you add group of spaceapi entries (location, sensors, ...)

I am trying something. Pushing in a new branch when done 👍
