fixes #766, fixes #842
* chore(package): update typescript to version 2.0.3

* Add customClass property to the Tab directive to make it easy to add class names to the outputted nav-items

* tslint fix

* Clicking on some tabs would sometime result in reloading the application (tested in Chrome). This will probably fix issue #842 which sounds exactly like the scenario this fixes for me.
