[O] version dependent org-links

[John Kitchin]

@neurolit suggested this approach for org-version dependent links in the
mu4e repo. I should have thought of that too! Its totally robust.

(if (fboundp 'org-link-set-parameters)
    (org-link-set-parameters "mu4e"
                 :follow #'org-mu4e-open
                 :store #'org-mu4e-store-link)
  (org-add-link-type "mu4e" 'org-mu4e-open)
  (add-hook 'org-store-link-functions 'org-mu4e-store-link))
