Overlord

I tried to address all comments and feedback from last code review by Joe.
I installed the selenium-driver for capybara and refactored views to invoke actions directly from javascript.
I separated test features into logical buckets and paid attention to happy/sad/error order.
given that your activation/deactivate steps are worded as `When I activate the bomb`, i'd word this step as `When I detonate the bomb` just to be consistent
