fix(ngAnimate): support removing classes from SVG elements when using jQuery

Fixes a regression in ngAnimate introduced in 2f4437b3, whereby SVG elements would not be able to
have classes removed by ngAnimate methods when jQuery was loaded (without also including libraries
which patch jQuery to support SVG elements, such as jquery-svgdom.js).

This fix exports jqLiteHasClass as a private method `$$hasClass` on the `angular` global object,
which enables ngAnimate to use this SVG-safe method for testing if the class is available.

fix(ngModelOptions): do not trigger digest on `setViewValue` if debouncing

Note that this change means that anyone watching `$viewValue` will have to
wait for a new digest before they are aware that it has been updated.

chore(package.json): tidy up dependencies

Sorted dependencies into alphabetic order. If we can keep them like this
it will be much easier to keep track of version changes.

Updated bower and gulp to newer versions.
chore(bower): refactor bower usage

The gulp bower task in the docs app was never actually running since it couldn't
find the bower.json file and was silently failing. Updating to a newer bower
highlighted this issue.

This commit moves the docs app specific bower components into the docs folder.
There are only jquery and closure compiler related components in the project
folder now.

It also improves the gulp bower task to provide better feedback of progress
and errors.
docs(form): move param tag outside of main description
docs($filter): remove duplicate documentation of register method
refactor(select): remove code duplication
