Subject: [PATCH] enex: Convert OneNote (via Evernote) todo images to Unicode
 checkboxes (#2189)

When a OneNote todo bullet is imported by Evernote it is converted to an
image showing the checkbox the way it looked in OneNote. This change
takes advantage of the consistency of that image hashing to convert
those images into unicode checkboxes (matching the existing ENEX
<en-todo> behavior) . It also removes the image attachments.
