Convert Deluge Plugins to GtkBuilder

[Cas]

The plugins needs converting from libglade to Gtk Builder. It is a fairly simply process with the following steps:

Glade file conversion

1. Open <filename>.glade file in Glade 3.8.1 UI designer.
2. Choose Edit | Preferences
3. Change Libglade to GtkBuilder and 2.24 toolkit.
4. Then File | Save As... and change filename extension to .ui. (e.g. <filename>.ui)

PyGtk code conversion

• Remove any gtk.glade imports
• Replace glade.XML with Builder instance and add_from_file method, for example:

-      self.glade = gtk.glade.XML(get_resource('<filename>.glade'))
+      self.builder = gtk.Builder()
+      self.builder.add_from_file(get_resource('<filename>.ui'))

• Ensure .glade files are renamed to .ui equivalents.
• Replace glade.get_widget with builder.get_object
• Replace glade.signal_autoconnect with builder.connect_signals
• If the naming of handler methods match the signals it is possible to use builder.connect_signals(self) instead of specifying the mapping.
