Generic landing page
What does this MR do?
Replaces the festival image on the landing page with gabel.png and places a generic foodsharing text next to it. (Feel free to change this to something more appropriate)
Needs to be merged to production as well (or cherry picked or whatever) to get rid of last week's festival on the landing page soon.
How confident are you it won't break things if deployed?
