[Request] Add support for Browserify

[jkjustjoshing]

When the AngularJS team releases angular-resource, angular-sanitize, etc, they include a file index.js at the root of the project that requires the actual js file, and then exports the module name. This allows you to require the library in the following way:

angular.module('myModule', [
    require('angular-resource'),
    require('angular-sanitize')
])

Since the dependency exports the angular module name, it is equivalent to writing:

angular.module('myModule', [
    'ngResource',
    'ngSanitize'
])

Think we could add this to angular-bootstrap-datetimepicker? I'll create a PR for this just in case you're up for adding it!
