Rename the app-id to org.gnome.Settings since this is what
we've been calling it for many years now. Adjust all files
that derive from the app-id, such as the desktop file, D-Bus
service file names, search providers, GSettings schemas, to
match that.

Both the Network panel and libnma expect UI resources in the
same location, which will cause problems when the Network panel loads
its own version that doesn't quite match up to the code used in libnma.
This fixes a crash when nma_wifi_dialog_new_for_hidden() is called and
libnma expects a domain widget to be present, which it isn't in our
version of the UI files.

This code is fairly independent of the rest, and we don't want
net-device-wifi.c to become too massive and unmaintainable.
The code in connection-editor/ is fairly similar to
nm-connection-editor, with some simplification because we
currently only edit wireless connections.
The code in wireless-security/ is almost a straight copy
of the same code in nm-connection-editor, with some changes
to the .ui files to make them fit better in the new design.
