Method to improve Angular.js's handling of module definitions without modifying angular itself.

(function(window, angular) {
    'use strict';

    /**
     * Register or fetch a module. Angular doesn't handle modules in this way usually, overriding the module instead of
     * extending it. So controllers/services/directives/etc can't share the same namespace without separating the
     * module definition from the module implementation, leading to files with one line in them or one file of module
     * definitions.
     *
     * @param name         {string}   Module name.
     * @param dependencies {Array}    List of modules this module depends upon.
     * @param configFn     {function} Config function to run when module loads (only applied for the first call to
     *                                create this module).
     *
     * @returns {*} The created/existing module.
