The first input source gets activated by default when users log in but
we don't currently allow users to set this (other than the awkward
remove all input sources and add them again in the right order).
Allowing user re-ordering of the input source list nicely allows users
to get the default input source they want.

Currently it looks a bit unpolished that the add/remove buttons on the
other side of the toolbar look linked while this pair doesn't. Note
that the input source settings button isn't always visible but in that
case the layout button will still show up correctly as non-linked.

Otherwise we could fail to validate the new configuration depending on
which output we're initializing mirror mode from.
gnome_rr_config_applicable() creates a temporary array of outputs for
validation and, in clone mode, all of them are assigned the same
geometry but, since it lacks context about which output the user is
currently on, it just uses the first one's geometry for all of
them. If this first output isn't the one the user is changing in the
UI then we never called _set_geometry() on it with a clone mode
geometry and thus the validation would fail because the geometry used
is that output's current mode which might not match the clone mode's.

It is possible to press the Add button in the custom shortcut dialog
when the name and command fields are empty. Disable the button by
default, and only enable it when the name and command is non-empty.

The call to nm_setting_connection_get_zone() returns a pointer to
memory that will be freed before the D-Bus reply handler is called.
Make sure to take a copy of the string, and free it when finished.
