As part of the cleanup I started working on a rewrite of the viewer code.
The todo, memo and addresswidget will be rewritten so that they share code that is common for all of them. The first step in this rewrite is to get rid of the PilotComponent code. All components are now based on ComponentPageBase and the viewers will be based on a subclass of ComponentPageBase which is called ViewerPageBase.

At the moment only the TodoViewer is enabled but not functional. The other page should work as before.
