New PredefinedStep: WriteViewpoint. Non-admin users may need to create

or replace named viewpoints during ordinary Item workflows. Previously,
AddC2KObject was used, but as that is now Admin only, a new step is
necessary to do this. Unlike the admin step, this checks that the target
Outcome and Event exist and are of the correct schema before the
Viewpoint is written. Fixes #154. Refs #152
