[FR] Disabling/customizing background images

[luntik2012]

I don't think this is good readable

Please, make an option to remove backgound or to set custom weather related background images.

As a temporary measure, you can change the images for the backgrounds in the img folder, but this would be reset after every app update. If you can provide us with better pictures under a permissive license (like CC-BY-SA or CC-BY or Public Domain) this would be highly appreciated!
