state/province better if there is also a field manually

is better if there is another field state/province that isn't a select but a simple textfiled;
this because the box select isn't flexible: in the year is normally that in some nations change the situation
of the province (names, numbers, etc) and also in some nation isn't necessary insert a value;

the simple solution is to have a simple textfield;
who would like to use can disable the field select and activate the manually field;

at moment if one disable the field state/province anyway in the report remain a value N/A;
this is another problem to solve;

------
really in the admin settings there are two fields that aren't activate: Address and Street address;
you can see in admin/store/settings/checkout/edit/fields; I thinked , ok I change some in the code for to enable and use how alternative field;
but they aren't usable see that there aren't in the database uc_orders table;

other is that the new field province manually must to have the same position of the actual field province;
