Before this commit, when you had a lead coming from your website form, you
had no informations from where it was located.
It was especially painful for USA which should add customer their location to
know their timezone and know at which time they could call him.
Now, the state code is added to the created lead. It is easy to figure what
timezone the user is on without contacting him first to ask.
