Add jasmine testing and helpers

    With the integration of the AngularJS framework we need a powerfull
testing, Jasmine could be a good choices because of its great features
and it is the one which is described into angularjs documentation. It
will allow us to have good example for creating our tests.

    To create a test you just have to inherit JasmineTests class, and
specify the tests files to run (with their path) in the specs class
attribute. If some html elements are needed, just inherit from the
jasmine.html template and add them to the content block, to finish
specify the template in the test class into the template_name attribute.

Integration tests - running the tests

Initial setup for running the integration tests. A basic test is
included to ensure this works, although it will be rewritten to follow
the Page Object pattern. Thanks to Daniel Korn for the initial test.
