Adds information about duration, visibility and comment to agenda list view
Allows channg these information over a dialog component on the

fix disappearing submitters (hopefully)
- replaced "motion from form values" function with deserialize
- fix some typos
- make id id again
null, in contrast to undefined, will be send to the server...
Better typing and changed the create/update signatures in BaseViewModel
- use object as default type for BaseModel.
- use partial objects for updating
- Displayable should not have an id. Moved this into own interface
Identifiable and make the id in the BaseViewMotion abstract.
- create only takes a BaseModel. A ViewModel should not exists so far.
- Updated the update and create method for motions.
