chore(cleanup): Removes all the internal dependencies.

Various internal dependencies have been rendered out into specific external dependencies, to allow for Angoolar projects that are as tight as possible.

Some newly external dependencies are as follows:
- angoolar-resource
- angoolar-cookies
- angoolar-sanitize
- angoolar-ui-router
- angoolar-jquery

Usage of `root` and `root = window` has been deprecated. Everything related to `root` is now done through `angular`, and it never need be defined (like `angoolar = ...`).

All underscore-related dependencies have been turned into specific lodash functions that must be included in the Gruntfile.coffee/package.json build. The minimum set of functions for now is:  indexOf, union, has, without, debounce, throttle, keys
