Menus: Remove redundant title attributes.

Browse Source 
Omit `title` attributes if they are defined but are the same text as the menu item title, either before or after filtering. If a navigation menu filter makes significant changes to the menu title without changing the title attribute, this will still remove them. The cases where this occurs and the title attribute is still a useful value will be very uncommon, however.
