(1) Clarified directive e2e test result and (2) template referencing examples

In the first case, the use of 'angular' as sample text is confusing to the newbie (of which I am) in that they are force to confirm that the text 'angular' is not a keyword or otherwise referring to a system component. It is useful to ensure that sample text are obviously sample text.

In the second case, the introduction to the list of ways of referring to directives from the template was in obvious need to repair. I have also moved the most common example to the top of the list in companionship with the use close by of ng-model.
