support xfce wallpaper fetching

[eMPee584]

xfconf-query -c xfce4-desktop -p /backdrop/screen0/$(xrandr|awk '/\<connected/{print "monitor"$1}')/workspace0/last-image

That command is very unreliable. If a more reliable method is found I'll add it to master.

Maybe something like this? Works for me on a single monitor setup.

#!/bin/bash

workspace_number="$(xprop -root _NET_CURRENT_DESKTOP)"
workspace_number="${workspace_number#*= }"

xfce4_image=($(awk -F 'value=' '/last-image/ {print $2}' \
               ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-desktop.xml))

xfce4_image="${xfce4_image["$workspace_number"]/\/>}"

echo $xfce4_image
