Problem:
- There's not yet a way to get the parameters for each channel
after it's clicked

Three important changes:
- The FilterList is now the ProcessorList
- The FilterViewport is now the EditorViewport
- Any classes that need to access important UI objects have become subclasses
  of the "AccessClass". Such objects automatically obtain pointers from
  the UIComponent and register the MessageCenter as an ActionListener. This
  will make it much easier to allocate pointers to objects.

Because the WiFiOutputEditor also had timerCallback() defined, it wasn't able to
fade in upon creation. This method was modified to solve the problem.
