One translatable string contained the typo 'enterpise logins',
where it should have said 'enterprise logins'. Pointed out in
https://bugzilla.gnome.org/show_bug.cgi?id=684122
This commit updates the msgid in all .po files, so translations
should not be negatively affected by this string change.
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.
