Started the Events mixin test structure.
Moved blend to mixin and restructured.

So now there is no utils dir.
So now blend is mixin.

The mixin method mixes all passed objects except the first *into* the
first object. So you pass the prototype of a class first and then all of
your mixin objects after. It will mix all of the methods and values into
the prototype/object you passed as the first argument.
Added methods for getting events and listeners.

Also tested them. (Events mixin)
