Properly escape reference links before rendering

- Use org-insert-link method to improve link rendering robustness
  Previous simple mechanism to crete org-links would result in links
  escaping out of formating. Use a user-facing org-mode method to
  remove/reduce probability of this

- Replace newlines with space to render reference notes as links
