Pedro Algarvio dbad4684db Create torrent remotely progress information.
Support progress information when creating torrents remotely. For this to be possible, a method was added to the `RPCServer`, `emit_event_for_session_id()`, which does exactly what is says. This is needed because the event created, `CreateTorrentProgressEvent` needs to be addressed to a single session id, not all session ids interested in that event.
Fixed a bug that apparently was not found yet. When creating torrents locally, we defer that task to a thread. Since this thread updates UI widgets, namely the progress bar info and since we can't guarantee that it's the main thread, updating the widgets must be done by calling `gobject.iddle_add()`.
