docs($anchorScroll): provide an example of basic usage.

Per a request made by Peter Bacon Darwin here:  http://www.benlesh.com/2013/02/angular-js-scrolling-to-element-by-id.html?showComment=1370941217879#c8718313084813008967
docs(): parameter for html5Mode is boolean
docs(bootstrap.ngdoc): clarify bootstrap example

Clear up confusion about module declaration when using manual bootstrap.
docs(angular.bootstrap): clarify modules parameter

It was not clear what you could pass to specify modules to load in the
`module` parameter of this function. The `modules` parameter takes an
array.

The main case is to provide a String, which is the name of a "predefined"
angular module.
The side cases are to provide a Function (or an annotated function in the
form of an Array), which will be invoked by the injector as a run block.

It is not possible to "define" new modules via this parameter.

Closes #3692
docs(css_styling_guide): add ng-scope and ng-binding classes

I noticed angular was adding these css classes to elements and believe they
should be listed in the documentation at this page. The ng-scope class is
mentioned in the developer guide, hence the link there, and the ng-binding
class is not mentioned anywhere else in the documentation or the guide that
I found.
