bbox: unload pics/vids from DOM; closes #71

Browse source 
videos unloaded correctly when switching between files, but not when
closing the lightbox while playing a video and then clicking another

now, only media within the preload window (+/- 2 from current file)
is kept loaded into DOM, everything else gets ejected, both on
navigation and when closing the lightbox
