4473 Kiosk Update

new feature Customers can now go to the Kiosk to sign and recertify.

improvement If a customer is manually entering their 4473 code, they can type in the 4473 number followed by their last name, the system will not require the full last name if the last name contains periods or a suffix.  

In general, we highly recommend a scanner at the kiosk.   A 2D scanner on Amazon is less than $50.

fix Sec B/21.L.2 Canto be left blank if US Citizenship is picked.
