improve <script type="text/ng-template"> docs

[drewpca]

http://docs.angularjs.org/api/ng.directive:script is broken:

• the demo is floating above the demo box
• the displayed demo code is incomplete

It would also be nice if "$templateCache" was a link to http://docs.angularjs.org/api/ng.$templateCache , which has some good information.

The question I came to the page with was: how do I specify an in-page template for my directive? The answer is templateUrl: 'id_of_script_tag_here', which I found by outside examples and guessing. (I thought it would be template: 'id_of_script_tag_here'.)

The PR added missing info to make the doc more complete. For the broken demo, it's caused by improper closing of the script tag which should be separately addressed (#5648).
