Modify stretch background image functionality (#198)

Browse Source 
* Modify stretch background image functionality

Changes the stretch functionality to fill out
the playlist background completely by zooming
the image (if keep aspect ratio is selected)
instead of filling it only height-wise.

* Add option to keep old background fill

* Fix playlist background image width and height

* Fix width calculation

* Remove old calculations
