chore(ngSanitize): extract $sanitize, ngBindHtml, linkyFilter into a module

Create build for other modules as well (ngResource, ngCookies):
- wrap into a function
- add license
- add version

Breaks `$sanitize` service, `ngBindHtml` directive and `linky` filter were moved to the `ngSanitize` module. Apps that depend on any of these will need to load `angular-sanitize.js` and include `ngSanitize` in their dependency list: `var myApp = angular.module('myApp', ['ngSanitize']);`
