Pull request to add a couple small features

I added in the ability to input the street address only, without the city and state. It simply concatenates the street number and route fields so the result is:
123 Main St
instead of
123 Main St, Anytown, USA

I also added in the functionality to change the value of a select box. If the detail is set to be updated in a select box, then it will find an option that matches either value or text. This works with or without options nested within optgroups. If no match is found, no change is made.
