Creates markdown links to the currently selected Apple Mail messages and copies them to the clipboard

selected_msgs_to_urls.scpt

--E.g., if you have a message selected that has subject and body:
--  Subj: Meeting about the Foo!
--  Body: whatever
--Running this script copies to the clipboard the string:
--  [Meeting about the Foo!](message://<some message id>)
--If you click on the resulting url, the message opens in Mail
--
--Basically, this is for getting links to emails into a todo list / task manager
