[dw-nonfree] Create S2 function to parse image properties

[afuna]

[commit: http://hg.dwscoalition.org/dw-nonfree/rev/5e8b455b9796]

http://bugs.dwscoalition.org/show_bug.cgi?id=1922

Refactor the image url generation (for relative paths) to be a function. Any
background image passed to generate_backround_css() is automatically
checked, and any others can be manually checked with:

var string image_url = generate_image_url( $*image_property );
