[ui] 3DViewer: make 'visible' property drive media load request

Browse source 
* remove the notion of manual media (un)loading from high-level UI
* visibility button now drives media loading:
   * if media is not available (not yet computed), it will be loaded once available if visibility is on
   * once loaded, media can't be explicitly unloaded 
* use an icon to indicate that the media is not available instead of colors
