menuUser.ctp assumes plugin will only link to itself

The file app/View/Elements/menuUser.ctp has code like this:

$args = $menuContent['plugins'][$plugin]['coperson'][$label];

$args[] = 'copersonid:' . $co['co_person_id'];
$args['plugin'] = Inflector::underscore($plugin);

print '<li>' . $this->Html->link($co['co_name'], $args) . "</li>\n";

So even if the plugin developer has explicitly set 'plugin' in the array to be some other plugin like the KdcAuthenticator, e.g.

array(
'plugin' => "kdc_authenticator",
'controller' => "kdcs",
'action' => "manage",
'authenticatorid' => "2")
)

then the code above will overwrite the plugin developer's choice for 'plugin'.

The effect is that a plugin may only have menu links into itself or core code, but not other plugins.

The code should allow the plugin developer to specify a plugin. It could, for example, test to see if $args['plugin'] is already set and if so do not override it.
