Meaningful account-less (empty/fresh) roster
Empty account-less roster.
Place first page of Account Creation Wizard dialog (Edit > Accounts > Add) to empty roster as seen in a printer-less system-config-printer.
Do not place buttons Cancel Back & Forward, just an Add button.
Selecting "already" (1) or "register" (2) would prompt to second page of Account Creation Wizard dialog and from that second page, where buttons Cancel Back & Forward are available, user would be able to turn back to regular first page of Account Creation Wizard.
Since there are no new strings, this can be done in 0.16 release.
