Thanks for this patch, bu I don't think that we should go this route of doing everything manually in the indicator and plug.
The GNOME Settings Daemon already provides an interface on the session bus org.gnome.SettingsDaemon.Rfkill, we should start using it as it would allow us to have the state synced across all the components without much hassle.

previously I used the dbus method call org.gnome.SettingsDaemon.Rfkill then I kept trying for a few weeks, at one point I tried to turn on and off bluetooth org.gnome.SettingsDaemon.Rfkill didn't respond. and I tried to read the properties using d-feet and it doesn't change. then i unblock rfkill manually bluetooth it works. and org.gnome.SettingsDaemon.Rfkill still does not show changes until the new restart works.

Closing as "Design Conflict" as the branch it depends on has already been closed as such. Thanks for your contribution anyway.
