docs(ngCookies): use GFM code-snippet rather than example tag

The example tag creates a big ugly white rectangle on the docs page, and this is not very helpful
and kind of looks bad. So GFM snippets are a better way to go.

This fix also removes the unnecessary example heading from the $cookieStore page, as there has not
been an example use of $cookieStore for 2 years now.

Closes #7279

fix(grunt-utils): ensure special inline CSS works when `angular` is not a global

The build includes a little script to angular.js, which adds some CSS styles to
the page to support things like ngCloak. This script checks that angular is
not in CSP mode, but before this fix assumed that angular would be in the global
scope.

This commit, references `window.angular` instead of just `angular` because when
running angular in an environment where the top-level scope is not the window
(nodejs for example), we angular is actually a property of `window`.

docs(select): improve naming of `c` variable in example

It was felt that `c` did not make it clear what the variable held. This
has been changed to `color` to match the ng-repeat expression above.
In turn the model value has been changed to `myColor` to prevent a name
collision.

docs(orderBy): clarify how sorting is processed

An API was passing me numbers as strings (ex. '8.25'), and I was noticing
weird sorting behavior with `orderBy` because it was trying to sort the
numbers alphabetically.

docs(examples): don't attempt to convert example content from JSON

There are some files in the examples that look like JSON and the default
$http transformResponse handler was trying to convert these from strings
to object. An example was the style.css file in the
https://docs.angularjs.org/api/ng/type/ngModel.NgModelController docs.

This commit fixes this by simply removing this transform when loading
these files.
