Setting the default icon name causes that it's applied globally to all
newly opened windows in the process, not just for the applet's windows,
so it cannot be used if the applets are built as in-process.

Handle the delete-event to hide the preferences dialog instead of
destroying it when the window is closed using the title bar's close
button. This allows the existing dialog to be presented again when
the preferences are opened.

The translation domain needs to be set before loading GtkBuilder files
to get the translated strings when the applets are built as in-process.

DriveButton connects a "changed" handler to the global default
GtkIconTheme but drive_button_dispose() never disconnected it. The icon
theme outlives the button, so after a button is destroyed (a volume or
mount is removed) a later "changed" emission runs the handler on freed
memory and schedules drive_button_update() via an idle source, crashing
the panel with a use-after-free.

Disconnect the handler in drive_button_dispose().

Add a new preference to force fixed size on all notes to prevent
resizing. Also fix a bug where notes taller than the screen height would
not display scrollbars after applet restart.

Fixes #370

When a network interface is disabled at the kernel level, the applet
tries to read from a device that no longer exist, generating continuous
warning messages in syslog.

Check if the device exists before calling glibtop_get_netload in both
is_dummy_device and get_device_info. When the device doesn't exist,
get_device_info returns a non-running device info, allowing the existing
auto-change logic to find an active device.

Fixes #688
