Subject: [PATCH] Support Gemfile in ember-cli application

Some EmberCLI addons require gems like compass or susy to be installed.
There is no need to have these gems in the rails project's Gemfile.
This pull request adds the support for Gemfile in the ember-cli
application's directory.

Tested with:

  - rvm 1.26.10
  - ruby 2.1.3
  - rubygems 2.4.5

Caveats:
  - the ruby version in both ember-cli and rails applications must be
  identical

We can reuse the exec method
