Scaffolding for e2e tests

 - A server that can create & dynamicaly mount a loopback application
   with a configurable set of models.

 - Server-side handler returning lb-services script (Angular SDK)
   generating for the loopback app configured by the test.

 - Karma + RequireJS + Angular configuration for running E2E tests
   from the browser.

 - Glue for setting up a loopback app remotely, loading the lb-services
   file into the test running in a browser and configuring
   Angular $injector that can resolve $resource models provided by
   the lb-services file.
