Update changelog for angular_router to 1.0.0

PiperOrigin-RevId: 164479795

Add automated testing of _tests and angular_test to travis.

* Only test on Dart stable for now. Let's get this working 1st.
* Start XVFB (thanks Gary!) and download/"install" Dartium.

Misc changes necessary to land this:

* Renamed the generated files in test_files from .dart -> .check
  * Otherwise the analyzer would scream about these files locally
* Reflection remover considers "main()" to be an entry-point
  * Removes the need for explicit @AngularEntrypoint() in tests

Closes angulardart#534.
