when debugging, load some Javascript libraries from a local copy (helps when I'm on the train)
customize pages based on the user's own congressional district

* move the what-district-are-you-in HTML into a new template file
* add a map to the what-district-are-you-in modal so the user can correct an incorrect geocode by dragging a marker
* if the user is not logged in, show the question and save the answer in a cookie
* centralize the map javascript across the modal, the old map page, and the new state page
* let the district be modified from the account profile page
* add a global callback mechanism for when the user updates his district
* on bill pages show at the top if the sponsor or cosponsor is one of the user's MoCs
* on vote pages, show at the top how the user's MoCs voted
