Module loader added to ify project.

Lazy-load modules into angular. In angular modules can only be injected once, on startup. This module loader loads the module into angular when needed. Examples are in the commit. 
The workflow is: (1) load the module with require (2) load the loader with require (3) load the module into angular with `load.module('module-name');`. It can be used to load external modules such as a angular-ui element only when the module is needed.
