Implements a new design that improves the user experience:
- add a clear cancel button
- add an indication the note is optional
- change the plus icon to a search icon
- show an error when the user tries to assign without choosing an assignee
- move suggestions to default search results
- focus search input when modal is displayed
Adds a new plugin setting that when enabled adds a status field for every assignment. This setting defaults to off.
The possible status for an assignment are customizable via yet another new setting, and the first one on this list will be the default status for new assignments.
The status is not yet show anywhere except the assign modal and the small action posts in topics at the moment. Adding status to the assignment list for users and groups will be handled in the near future.
