Load image attachments from live conversations.
MessageAttachmentTile automatically downloads image attachment thumbnails when
missing.
PhotoViewFragment first loads thumbnail, then loads the full image. Shows and
hides the progressbar correctly.
Added ability for UiProvider to specify which rendition of an attachment to
download.
