Add an getViewModelListBehaviorSubject that simplifies
how to get most model lists in the view
unified update, delete and create methods and removed redundant code from the repos
(where it was possible)
cleaned up the motion detail to not directly use the DataStore
Add information about the "main model" to all ViewModels, to call the
correct constructor in the BaseRepo
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.
