links_use_adminlevels setting ignored for admin menu

[chuyskywalker]

It seems that, while we have access to the option of "links_use_adminlevels" this change is not reflected in the menu of the admin pages.

Despite setting it to "false", my level 1 users don't see the menu option - however, they can upon direct linking, user the links page.

This is also the case for "links_minadminlevel" setting.

It's a pretty simple fix inside of the menu.php (see additional info for the fix)
