Subject: (create_okcancel) try to better fit both install teams needs and
 interface team one's:

- in the installer, all windows run under $::isWizard due to design
  stuff (wizard aspect and wizard mode should really be really two
  differents options for cleanity but that's postponed);
  o so to prevent ok/cancel buttons to be pushed at the right edge
    when we're asking a question instead of being in a wizard step, we
    add an empty label between the ok and cancel
  o we still put an empty label in wizard mode when not in the
    installer so that help/cancel and next/previous buttons packs get
    separated as requested by interface team

- we add an empty field when cancel/previous button does not exists so
  that when there's only one button, we prevent it to be centered (eg:
  "finish" in wizards);
  note that if $::Wizard_no_previous is not set, the button is still
  centered so that we keep some flexibility
