If we take the below facts:
- The country select is set as disabled
when Shipping is set to "Ship to the same address"
- The disable property of select inputs is
removed when shipping is set to
`create a new address`:
In `website_sale.js`:
```
$selects.attr("disabled", value <= 0 ? null : "disabled" ).prop("disabled", value <= 0 ? null : "disabled" );
```
We can safely assume that the select input "State / Province" was supposed
to be set as `disabled` in the first place, not as `readonly`
Before this revision, State / Provice was greyed when choosing
"Create a new address" for shipping, and selecting the United States
(but the select input was still usable, though, it was just greyed)
