Updated Helmsman to version 0.2.0!
Additions:
- Special meta-data predicates ns.
- Updated navigation fns to handle preds.
- Starting to update code with the assumption that we don't want a ring request.
- Added coveralls.
- Updated .travis.yml
- Updated navigation test to reflect nav changes.
- Updated helmsman.clj with "defhandler" and "handler" macros.
  - These macros will let you do compojure/clojure-like destructuring on the request.
  - This uses compojure.core/let-request macro, nothing more.
- Updated helmsman deps with most recent versions and proper exclusions.
- Removed clout from project deps (we're not using it yet.)
