fixed pagination bug not extracting tweets after first page

[xeliot]

Fixes issue (#101)

Brief summary of how I fixed it by modifying tweets.py:

Change r = session.get(url, headers=headers) to r = session.get(url+'&max_position', headers=headers). This allows response json to return min_position parameter which will then be used as the max_position parameter in the next session.get

r_json = r.json()

Change r = session.get(url, params={'max_position': last_tweet}, headers=headers) to r = session.get(url, params={'max_position': r_json['min_position']}, headers=headers).

This gets rid of twitter pages repeating on search query.
