Add State Selection to Location Modal

[manifestinteractive]

Overview:

Let's add a state selector to the top of the city selector popup so people can find everything from this interface.

Acceptance Criteria:

Issue will be considered complete when the following criteria are met:

• Update Modal for Department Selector to Contain State Selector
• When user selects a State, the list of departments should update for that state
• When the modal window opens for the first time, the current states data should always be selected
• When the modal window opens for the first time, the current location should be selected and scrolled into position

Documentation:

Screenshots, Attachments, Linked GitHub Issues, etc

These are the two separate bits that we would like to combine together inside this modal. We can leave the state selection at the top, but we're just duplicating it inside the new modal.

Dev & QA Notes:

Any additional notes from developers or QA required to complete this issue.

Currently there is no other state data available on the page, as it is only loaded with the current states info. We will need to add some AJAX based method of loading these other departments when the user switches states.
