Rill finds peers through the DHT much sooner. It sent no more than ten DHT queries at a time, so searching for a torrent's peers waited behind the node's own upkeep and often found none. Rill now uses mtorrent 0.7.2 and starts fewer threads.
Uninstalling a build from source refreshes the icon cache, so removing a per-user install no longer leaves Rill without icons when it is also installed for the whole system.
