removed existing geocoding/SMD-lookup, dropped in the MAR findLocation2 endpoit; NB: 'use my current location' now broken
added back support for 'use my current location' -- using the govtrack endpoint
fixed bug in xhr error callback -- should be 'error' not 'failure'
Merge pull request #121 from JKesMc9tqIQe9M/mar-geocoding

Use MAR "findLocation2" endpoint for SMD lookups
