Merge local and recent modules. (0.1.1a)

In order to add location and time constraints to the same query,
parameters must be passed to the same Twython function and,
subsequently, Twitter API call. Time-based queries remain unsupported
due to the way Twitter manages Tweets. Also, Twitter does not seem to
support search filters based on content type, so querying for a certain
kind of media may require manual filtering after receiving data back.
Constraints for proper query formation have been added to prevent
invalid queries from decrementing any rate-limit Twitter has imposed.
