add rudimentary location support

The function dbfp_query_location_name performs the location.name query
and returns a list of all stations that match the search term.  The
implementation has two flaws:  there is no URL encoding, and
malformatted query results will not lead to a meaningful error message.

There are two new test cases:  basic tests some basic functionality, as
setting the API key and accessing the API.  location adds a simple test
for the location.name query.
