Title: Removed dependency on a global Handlebars instance

A local instance of Handlebars can be passed to Ember by defining an Ember.imports object before requiring/loading ember. Doing so was causing an exception to be thrown by a file that was assuming that Handlebars existed globally. This fixes that.
