upgrade to bultitude 0.2.1 to stop relying on bultitude private fn

The only other noticeable change bultitude has had is [upgrading dynapath](https://github.com/Raynes/bultitude/commit/2353b1f24cf359cd707015d7394e3fdec75c9363). All tests pass except 5 errors which is same as master. Side note, should `lein test` be returning an exit code of 0 when there are errors?
