Add some protologs for window organizers & shell

- Refactor out base protolog impl so that shell can have it's own
  implementation which takes a different viewer config (from the resources
  directly instead of a separate file in /system/etc)
- Setup the protolog transform for shell classes
- Add some basic protologs for displayarea/task organizer controller
  & shell task org (for now only text logging)
