Upgraded to clojure 1.6.0
Fixed bug where all radio buttons with same name attribute are returned.
Put overall project version back to 1.4, use :^replace overrides for version profiles and added dev profile with version 1.6
Radio button selector now matches on both name attribute and value attribute
Fixed typo in test description
Merge branch 'master' of https://github.com/johncowie/kerodon
