[FIX]Quick usability fix. According to the discussion in the developers list, make selection of profiles in an early step of the wizard, and make its links open in new windows so that admins can continue fine tuning their tikis with the wizard in the first window. Profiles set to the 3rd page, because the 1st is language, and the second (time/date, or eventually could be another one) is needed for the language change to take effect after the second "save and continue". Thanks alain and others for the feedback in the developers list.
