[O] org mobile - pre hooks

[Richard Riley]

Could I suggest that org-mobile-pre-push-hook is processed at the start
of the org-mobile-push function before the checks? That way it can be
used to properly setup mobile e.g using auth-source for the mobile
password.

  (add-hook 'org-mobile-pre-push-hook 
              '(lambda()
                 (setq org-mobile-encryption-password (funcall (plist-get (car 
(auth-source-search :host '("orgmobile"))) ':secret)))))
