Add standard Dictionary object

[getdave]

Add a standard Dictionary object to the framework.

(function() {

    var Dictionary = function(startValues) {
        this.values = startValues || {};
    };

    Dictionary.prototype.store = function(name, value) {
        this.values[name] = value;
    };

    Dictionary.prototype.lookup = function(name) {
        return this.values[name];
    };

    Dictionary.prototype.contains = function(name) {
        return Object.prototype.hasOwnProperty.call(this.values, name) && Object.prototype.propertyIsEnumerable.call(this.values, name);
    };

    // Register widget
    SITE.utils.Dictionary = Dictionary;
}());

Please note that due to the order in which the JS is compiled by Grunt all utils needs to be defined in the globals.js file.
