Alters the user detail view and the list of speakers to
support the gender field.
Default selection of genders was set to "Female", "Male"
and "Diverse".
Adding genders to users is completely optional
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.
