setup.py -
- Incremented minor version to 0.8.10 due to bug fixes. (latest release on github is 0.8.8)

examples/readme -
- Updated the documentation for FilteredStream class to reflect change to class.

twitter_stream.py -
- Removed .json() on line 185 as get_rules returns the appropriate object already.
  .json() was causing delete_all_rules to not work correctly and not error.

- Added _has_params = True to FilteredStream class to allow adding expansions to
  tweet objects. Documentation in examples now reflects this.
