Changed test suite to use mocha for #10; WIP

Update the test suite to use Mocha. This tests results in creation of
the model objects in /models. The ultimate goal is to create unit tests
that are not dependent upon the actual database, in order to enforce
separation.

- package.json - Changed the npm test command to use a test runner named
  `test.js` which starts mocha with some configuration options set. Also
  added other packages to be used with testing, including:
  * lodash
  * factory-girl
  * factory-girl-sequelize
  * faker

- test.js - Test runner starting Mocha with standard options.

- specs/index-spec.js - Old supertest based test that no longer applies.

- specs/models/AccountSpec.js - Unit test that checks the functionality
  of the Accont model.

- models/Account.js - Changed the jshint to use 4 spaces.
