Added wrappers and updated deps:

Updated clojure version to same as other projects
Updated midje to latest version
Added json input and output wrappers
Merge branch 'master' of https://github.com/obohrer/octia into feature-add-json-wrappers

Conflicts:
	project.clj
Merge broke tests because midje was missing joda time
servlet dep should be in dev profile as it's there for ring-mock
shouldn't remove raw body field
Merge pull request #2 from smallrivers/feature-add-json-wrappers
