Network Wizard fixes

Firstly, the 'p11-kit' has been added, required by a couple of AppImages.

Major changes to the Network Wizard (NW)...

Package 'ethtool' added, needed by NW to detect alive ethernet cable.

Fix for NW not automatically connecting after a reboot.

The NM scripts use a translation technique from the very early Puppy days. Changed to gettext.
