On panel construction, we trigger asynchronous creation of a GDBusProxy
for the IIO sensors daemon and one for the Screen g-s-d interface.
Since there's no guarantee we'll have the screen proxy ready by the time
the IIO proxy is constructed, guard for (priv->screen_proxy != NULL), or
we'll hit a critical.

Going back when the back row just gets selected breaks keyboard
navigation. This behavior got introduced by mistake in commit
f28e06a4. Instead, let's just do the add button sensitiveness logic
here. The back row still works when activated.

For newly created user accounts, AccountsService won't have the
language property set. Instead of defaulting to en_US in that case,
let's fallback to the current locale.

On systems that have only a few locales installed we might end up
starting with an awkwardly small height. To avoid that we can set our
initial height to be the same as the main window.

Remove the GList holding printing devices and use already present
GtkListStore for this in the New printer dialog.
This avoids us to install wrong printer when there is more devices
with the same name since we have GtkTreeIter of the selected row.
Use GtkTreeModelFilter for filtering of current devices.
Update test for canonicalize_device_name() since I had to change one
of its parameters.

We now offere separate "Bluetooth is off" and "Airplane mode is on"
pages. The "Airplane mode is on" offers to turn off airplane mode
altogether.
We also have better explanations for all the other modes, and a filler
Bluetooth logo to make the page seem less empty.
