[ENH]New screen in the Upgrade Wizard to provide feedback and use the Tiki Connect feature. Checkbox to Provide feedback shown in the wizard bar on top. Couldn't fully test it in trunk since the Connect feature itself doesn't seem to working in trunk nowadays. ToDo: add a way to show the buttons next to the profiles in the Profiles Wizard, as well as next to the Start Wizard Buttons in the Tiki Setup page.
