Subject: [PATCH 1/2] docs(tutorial/2 - Angular Templates): Running unit test
 without Firefox installed throws error

I am following the tutorial on AngularJS website. However I got an error when running the provided unit test without having Firefox browser installed on my machine.

Console output:
```
INFO [karma]: Karma v0.12.37 server started at http://localhost:9876/
INFO [launcher]: Starting browser Chrome
INFO [launcher]: Starting browser Firefox
ERROR [launcher]: Cannot start Firefox
	Can not find the binary /Applications/Firefox.app/Contents/MacOS/firefox-bin
	Please set env variable FIREFOX_BIN
INFO [Chrome 46.0.2490 (Mac OS X 10.11.0)]: Connected on socket zZ0c0QemlSHXzVaqVGqC with id 90305753
```

I guess it will be much clearer if we also pointed out these browsers requirement on the tutorial documentation.
