Angular Phonecat test suite using page objects.

[avandeursen]

Revision of the test suite to make use of page objects. The page objects are derived from the state chart shown below.

This design is used in order to make the scenarios more robust and easier to follow, since the Protractor details are hidden in the state objects. Furthermore, the diagram guides the design of the actual scenarios.

Note that the state object methods return promises.

Note: To get the existing tests to work I also had to use the fix in #267. This is independent of the use of page/state objects.
