fiddle with imtext box size
remove jinja extension of base.html for 404 and 500 since it currently requires a form arg
added table with pano info for debugging with DOM inspector
improve StreetView pano guess position

previous approach getPanoramaByLocation returned many cases with
indoor imaging from a neighboring store. Instead, now we use jquery to
call a python function which uses an unofficial Google API that
returns the best-guess outdoor pano ID. This should be used as a
starting point for StreetsAhead location/orientation as well.
add get_pano which parses xml file to get unofficial best outdoor pano from Google
