Subject: [PATCH 161/161] Gracefully handle hamster DBUS disappearing

Previously, if this happened the extension would be disabled using the
`disable()` method. However, this caused an error (because disable was
called twice, once for each DBUS service) and gnome-shell would not be
told that the extension was disabled, so the user could not re-enable
it.

With this commit, when the apiProxy disappears, the panel widget is
hidden. When it reappears, the panel widget is shown again.

Note that there are still some rough edges, but this change is mostly
intended to simplify hamster development - you can now restart hamster
after making changes (or to switch between installed and source
versions) and still have the extension work without needing to restart
gnome-shell (which means logging out with wayland).

This commit does not attempt to handle windowsProxy disappearing, since
keeping track of the status of both services can get messy quickly.
Also, now you can restart just the api service, and leave the windows
service to be autostarted when needed if you want (and if autostart
fails, the user will be shown a proper error message).

Also, this does not disable the keybindings, so pressing that while the
DBUS proxy is down will probably still allow opening up the menu (but
that's ok - making any changes will just autostart hamster again, or
show an error message otherwise).
