* Bug fix: reverify using fissix instead of ast to preserve the ability to modify code
  that is incompatible with the host version of python (#78)
* Log full traceback of errors during `bowler run` (#86)
* Adds a maintainers guide (#83)
* Changes `filename_matcher` to receive a full path, in case it needs to read
  the file separately (#81)
* Adds `query_func` to BowlerTestCase making it easier to test the provided
  helpers, and improve exception capture in tests.
