Add parameter to force Document tree to sort alphabetically by rendered title

Document tree is sorting results alphabetically by default, but pages with Velocity code in their title are ignored during the sort, causes mixing results (example: Blog page, AWM page)
One workaround for users who want to force the sort to be done on the computed title of the pages would be to add an option to some components showing Document Tree.
For example:

• Parameter to the DocumentTree macro
• Option in the Navigation panel (Panels.Navigation)
• Option in the administration for the Breadcrumb
