[REF]Refactoring of profiles in different Profiles Wizard Screens. Refactored names of files and functions to be more consistent with the naming of 'Profiles Wizard' aside of the 'Admin Wizard'. All this comes from discussions in the last TikiFestT13Alpha (thanks nelsonko). To be backported to 12.x after 12.1 is released.
