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
docs(ngCookies): added example usage of cookieStore

Closes #7278
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`.

Closes #7176
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.

Closes #7210
docs(guide/unit-testing): remove unwanted whitespaces

Closes #5395
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.

Closes #5436
docs(angular.Module): add link to `module.config()` docs

Add a link on where to find more info about how to use `module.config()`

Closes #6270
docs(guide): add another analytics library
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.
docs($sce): fix grammar
docs(directives): remove line numbers from code blocks
test(ngModelOptions): ensure input has focus in e2e tests

This was not failing on Travis or Jenkins but was reliably failing on my
local build.
chore(travis): update Chrome on SL to 34

For some reason, SL gives us Chrome 28 when no version is specified.
feat($compile): allow SVG and MathML templates via special `type` property

Previously, templates would always be assumed to be valid HTML nodes. In some cases, it is
desirable to use SVG or MathML or some other language.

For the time being, this change is only truly meaningful for SVG elements, as MathML has
very limited browser support. But in the future, who knows?

Closes #7265
chore(travis): use npm cache
revert: test(ngModelOptions): ensure input has focus in e2e tests

This reverts commit 8d38ec38921bf887189eb31b07855ca987beff47.
The protractor tests for ng-model-options were failing locally on Chrome
for me but this commit breaks the tests on Firefox.
chore(travis-build): don't re-package when testing docs

Since .travis is already running `grunt package` in the `before_script`
block there is no need to run it again when testing the docs.
