Setting directory as wallpaper doesn't work anymore about setwp

[fredericofernandes]

So it's not possible to set a directory as wallpaper source?

@fredericofernandes That's right. I'm working on the fix right now.

After some investigation, I found out that it's now required to set a current wallpaper as well as the directory. So this will require selecting a picture from the given directory and setting the Current preference (see pref.Current).

I was wrong there; that doesn't always work. Not sure why... Anyhow, I made that partial fix and updated the Homebrew formula. More investigation will be needed for a complete fix, but for now just run the command again if it fails.
