* Added the notion of "tag" to each effect which is a four char string
that identifies an effect better than an index.
* Added random access command '=' to SerialController.
* Use "={tag}" to jump to effect with tag.
* Refactored all effects to use the new EFFECT macro since it helps with
names tags and create methods.
