Add new wallpaper and change default wallpaper. T76
I have an inline question but it's not a FIXME so I'll go ahead and mark this as good.
Did you figure out the issues that were occurring with arc diff?
This reminds me; is your plan to keep the wallpaper we had as default for the past few releases in there? If not, please delete those files and remove this line.
Up to you, just thought I'd bring it to your attention.
