feat(crew): add prpagation of event change to event reducer

While the attendances, duties and events features are otherwise
separate, upstream changes to attendances and duties must be propagated
to the events list and therefore agenda feed. Events are:

 - A duty is created (CreateSuccess).
 - A duty is destroyed (DestroySuccess).
 - An attendance is updated (UpdateSuccess).

Changes:

- Modules
  - Add DurationModule
    - Encapsulate DurationComponent and DurationPipe. These are used
      together in duties and attendances
- Pipes
  - DurationPipe
    - Refactor. The original code threw an error when called as I used
      deprecated syntax. See linked GitHub issue for more information.
    - Update calling references.
- Builders
  - CalendarEventbuilder
    - Add ID getters for attendance and duty records. EventEffects use
      these getters.
    - Update internal refernces to use these.
- Effects/Reducers
  - Add EventEffects
    - Forward propagate appropriate attendance and duty changes to the
      events refucer.
- Add tests for all affected code.
