Don't require modules to return function

[rikschennink]

Use "new" constructor on Modules that return a function.

When an object is returned this object should have a "load" method which returns another object, this object should have an unload method and can be the same object as the object having the load method.

var exports = {
    load:function(element,options) {
         // do stuff
         return exports;
    },
    unload:function() {
         // clean up
    }
};
return exports;
