Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
rlgwebd.js: get rid of numerical game identifiers. Games will be indentified by gamename/username pairs. This will allow better interoperability with dgamelaunch. Polling clients are no longer supported; the code remnants need to be removed. The reaper() function will likely crash. Unexpectedly, the WebSocket client still works well enough to play. Watching and listing current games are probably broken.
