Replace workboard task creation with EditEngine
Summary: Ref T9908. This is the last of the things that need to swap over.
- Created tasks from a workboard.
- Created tasks in different columns.
- Edited tasks.
- Used ?parent=...
- Verified that default edit form config now affects comment actions.
- No more weird comment thing on forms, at least for now.
