* BBBikeTest: new test functions validate_bbbikecgires_yaml_string,
  validate_bbbikecgires_json_string, validate_bbbikecgires_data

  Also rewrote the validation function in t/cgi.t to use the new
  validate_bbbikecgires_data.
* cgi.t: use the json/yaml validation functions
* added at least one traffic light to the data-test directory
* bbbike.cgi: off-by-one error

  Routes with just two points in the path did not had a
  direction entry. This is now fixed.
