[Feature Request] Wallpaper notification matches with background folder name.

[schmurtzm]

It's sometimes difficult to match the wallpaper displayed to the corresponding folder. In addition there's now an empty/black background systematically available. Currently when we press "hotkey + Y" the notification for this empty/black background is the same as the last wallpaper available.

So it could be nice if :

• The bottom yellow notifications have a name corresponding to the folder name, which mean after pressing "hotkey + Y", if the folder is called "White NDS" for example the notification would be "Wallapaper: White NDS".
• The notification for the empty/black background would be "None"

For example :

This notification should correspond to resources/bg_640/1 (but a description name instead a number could be even better) :

This notification should be "Wallpaper: None" :
