This probably broke some behaviour because converting and splitting from libglade to GtkBuilder is not as perfect as it should be. What I noticed was fixed.
Also, GtkBuilder only allow calling `connect_signals()` once. Some code had to change to handle this and a "handlers proxy class" was created to keep the behaviour we had, ie, connect signals from where it was needed. Then I monkey patch the main windows GtkBuilder to not allow anyone to connect signals through it since it would break behaviour. Connecting signals to the main window builder instance is now done like `component.get("MainWindow").connect_signals()`. The best solution will probably break the main window ui into the needed parts in order to not have to monkey patch main windows builder.
Plugin's trying to get the main windows `main_glade` are now broken, on purpose, ie, the code they have needs to change since the calls to the builder are not the same as the calls to libglade. The plugins we ship with deluge will be fix as soon as possible.
Removing a column from the treeview on shutdown causes all the
column widths to be zero which are saved to the state file.
The workaround is to not save the state file if all columns are zero.
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()`.
Additionally creating a torrent and saving it on a remote path now mimics the behaviour on doing it locally. Need to evaluate to see if it's possible to also show a progress when doing this remotely as now, the progress is only seen when doing it locally.
