core: add "transparent" parameter to renderSVGIcon

The start-selection widget will need icons with a transparent
background so that the icons don't stick out like a sore thumb.

So far the icons rendered by this function were only used by
the images on the profile and were perfectly rectangular.
Therefore there was no need for this.
