Updates wallpaper to the current Bing wallpaper of the day
The python version no longer works. platform.linux_distribution() is deprecated. Also, the script was checking for Ubuntu instead of gnome for some reason.
Running the bash version will download the image to $XDG_PICTURES_DIR/bing-wallpaper and set the image as the wallpaper (gnome only).
Requires jq to be installed to work.
Wallpapers are saved with a timestamp, so the previous day's wallpaper does not get overwritten. Wallpapers can also be automatically deleted after they reach a certain age.
