Assignee field like Jira #2452 , in progress.

Added features:
- Assignee can now be added and removed.
- Avatar icon is at card and assignee details

TODO:
- When selecting new assignee (+) icon, list does not yet show avatars and names who to add.
  There is empty avatar without name.

Thanks to xet7 !
