Added delegate command to delegate existing actions.

* Created `delegate`. This will move an action from a next actions context
  folder to the waiting folder. Any duplicate items in project folders will be
  renamed and updated to reflect any action change.
* Updated `ls` to take multiple named contexts or projects and list them all.
