Spaces index design

[benediktms]

The following were fixed/added:

• Map stays fixed as the user scrolls
• Map does not clip through footer when less than a certain number of resutls get displayed from a search
• Search queries now get properly deleted when the user returns to the home page in the same sessions and looks at all available spaces.
• disabled turbolinks when looking at the spaces index page to stop the map not loading in
• Changed the design of the cards on the spaces index page to make them easier to read
• increased the market paddign to force the map to load a bit more data nd stop it from randomly not displaying sections
