This reverts part of f288367653 which
touches this file. I'm not entirely sure why it was changed, it looks
like a piece of refactoring that isn't complete yet, but MessageDelegate
still depends on a required room property.
Add a dev setting to allow relations to be sent to any message using the right click delegate menu. This shouldn't be a main feature, but since it's technically allowed in matrix this will help any future debugging
Create a new module for the room info drawer QML. This also requires moving some QML to LibNeoChat common with other modules. Finally all QML in roominfo is modifed to not depend on app.
