[test-time 0.1]: MockLifecycle: add phaselistener support

Writing a unit-test for phaselisteners at this moment means replacing the class
MockLifecycle. all PL-related methods just "throw new
UnsupportedOperationException();". The same applies to the execute and
render-methods.

It would be great to be able to

* tell the Mock-class how much time each phase "should take at least"
* tell the lifecycle to do
* a full run
* simulate a GET-call (just to restoreView and renderResponse)
* simulate converter- or validator-exception processing
* simulate the two calls from a portal container (means: start a processing
lifecycle, and later start a rendering lifecycle)
* simulate a navigation-action (change the view-id at the appropriate phases)
