support username logins for web selfcheck

    username login for web selfcheck

    Changes the behavior for the patron-login component (after staff login) to match
    the OPAC. By default, it assumes you are logging in with a usrname, but if the
    org unit setting 'opac.barcode_regex' is enabled and the incoming value matches,
    then it gets treated as a library card barcode instead. If usrname is used, then
    the card referenced by actor.usr.card is checked in lieu of a specified barcode.
