Added two scripts to change the wallpaper.

The one named "nitrogen" allow to change the wallpaper using
nitrogen. The one named "pywal" allows to change the wallpaper and the
terminal color scheme using pywal.
Both of them need to put the cursor over an image, there's no need to
select the file with space.
