This is a proposal patch in order to add support for randomly picked backround
image from a directory.
I did this because I'd like to have my TCEs load different pictures each time
they're on a bit like the welcome picture on Windows 10.
This patch only check if the --background parameter is a directory and if so,
pick randomly a SVG file from it.

Walid Moghrabi
