Get rid of ember-browserify dependency

[oskarrough]

Would be nice you didn't have to install ember-browserify to use this addon. But it's the easiest way I have found to follow the date-fns documentation on importing each function:

import closestIndexTo from 'date-fns/closest_index_to'

… but we can't import directly from node_modules with ember-cli. What to do?

@oskarrough Ember Apollo Client uses a WebpackDependencyPlugin
