GSD should have an option to show extra keyboard layouts

[Simos Xenitellis ]

xkeyboard-config has been remodelled and non-basic keyboard layouts have been moved to the 'extra' group.

Ubuntu does not offer a way through the GUI to enable the extra group for those users that need the special keyboard layouts.

How to replicate:
1. Click on System settings/Keyboard, then Layout Settings, then click on the [+] button to add a new layout.
2. Try to find the Avestan keyboard layout. Although it was added last year to xkeyboard-config, it is not shown in the list.

How to fix manually:
1. Start 'dconf-editor' (requires installation) and navigate to '/org/gnome/libgnomekbd/desktop/'
2. Find 'load-extra-items' and enable it.
3. Now the Keyboard layout list shows all keyboard layouts, including Avestan.

What should be done:
-> There should be an option in the Keyboard Layouts dialog box (in the Keyboard settings) to enable/disable the extra keyboard layouts.
a. The text for the checkbox could say 'Enable additional keyboard layouts'.
b. The checkbox action would enable/disable the field '/org/gnome/libgnomekbd/desktop/load-extra-items'.
c. The default should be not to show additional keyboard layouts.
