Check for null when there are no images
Check for null when there are no images

if I did something like "hubot image me ablederfl33wo", I would get an error like:

/opt/hubot/scripts/google-images.coffee:47
      images = images.responseData.results;
                                  ^
TypeError: Cannot read property 'results' of null
