Fix get_md() and parent assignments.

- now properly outputs category spacing in get_md()
  - removed task_spacing and note_spacing, may return later.
- fixed parent assignment, now iterates through the reversed children
  list.
  - this finds the closest parent.
- TodoObject now properly returns output with get_children()
