With HANDLES_COMMANDLINE, the commandline is handled in the primary
instance. That means two things:
- We cannot let GOption handle --help, since it calls exit() after
printing out the help
- The static booleans need to be reset to FALSE for each handled
commandline
This commit adds a new string, 'Show help options'. It also includes
existing translations for this string that were taken from GLib.
If NetworkManager knows that firmware is missing, say so.
This matches recent changes in the gnome-shell network menu.
It adds one new string, "Firmware missing", for which I have
pulled existing translations from the similar "firmware missing"
string in gnome-shell.
