Shell: fix handling of commandlines

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.
