experimental fix for https://github.com/vector-im/riot-web/issues/2985

Browse Source 
needs server to support 1600x1200 thumbnails for retina large ones.
ideally need to cap maximum thumbnail size to 800x600 rather than expand to arbitrary widths.
need to check that luke's funky timeline code doesn't get confused between naturalWidth and infoWidth etc.
also need to consider whether to encode a resolution metric in the event rather than lying about resolution.
