Add option to alter the More menu

[chrisguindon]

Jakarta.ee would like to remove references to Eclipse IDE In top-level navigation.

I am referring to Issue #103.

This is something that we must fix in the theme layer with a configuration parameter to enable/disable Eclipse IDE links in the more menu .

I think we also need an option to disable the more dropdown menu completely.

We separated the google search from the more menu. Sites can now override this layout to remove the more menu from the site.
