FileManager: Listen for changes to Desktop wallpaper in config
Since there's no global API for being able to just assign a callback
function to config changes, I've made an inline struct in desktop
mode with the sole purpose of checking to see if the Wallpaper
entry has changed, and then updates GUI::Desktop.
It's pretty neat seeing the wallpaper change as soon as you edit the
config file :^)
