This purifies the code a bit making the actual code agnostic of the environment it runs in. It also doesn't create useless noConflict method in cjs/amd environment

@emirotin thanks for the improvement. It's now available on npm as eventify@1.1.0, which also brings eventify up to date with the latest improvements and methods added to Backbone.Events
