[ingo] patch for ingo/templates/menu/menu.inc

[Gary Windham]

ingo/templates/menu/menu.inc doesn't properly handle the PEAR_Error
objects returned by Registry::link when the whitelist/blacklist features
are disabled in the registry.  This causes the links for these features
to be displayed on the menu bar, even when they are disabled.

Attached is a trivial patch that corrects this behavior.
