 timb:
 the ImgCache manages loading images and keeping track of image sizes...
 it can be passed a bunch of urls to load and a callback that gets called when more images are ready
 image loading can also be paused and started again.
 there can be separate ImageCaches, eg, one for search result images, one for chat images (but they all share the actual image cache)
 In theory it should also avoid a few http requests bc we can just dup DOM nodes for images that are already loaded that don't have cache headers (not sure tho, browsers probably pretty aggressive with that already)
