Currently menu items are shown in alphabetical order in applications and
no clear order in system configuration. This is done using static
weights for menu items based on English names that does not work for
other locales.
Sorting can't be done at the time of adding menu items as users of
multiple locales may use the interface at the same time.
Implement a sorting mechanism based on existing order as well as labels
of menu item. This allows the flexiblity of grouping menu items in
future as it may be need for system configuration. In case of help menu
Remove sort order for all modules except for help menu as here we want
that specific order.
