Provide js function in support of a lookup hook for wa_state_tax_districts

wa_state_tax_district()
* Checks form_address_info() to collect address data
* If any addresses are in Washington State,
* Uses misc/xmlhttp-wa_state-find_district_for_address.html to query
  wa state tax districting database
* Displays error, or updates the district input element for the addresses
* Calls submit_continue() upon success
* Calls submit_abort() upon error
