Empty response for Top Stories

[phamthanhnam]

For example:

from gnewsclient import gnewsclient
client = gnewsclient.NewsClient()

or:
client = gnewsclient.NewsClient(topic='Top Stories')
then:
client.get_news()
returned []

In gnewsclient.py file, function get_news(self), this line:
if self.topic is None or self.topic is 'Top Stories':
should be fixed by this line:
if self.topic == None or self.topic == 'Top Stories':
