[PATCH] Add new option 'org-imenu-flatten'

[Morgan Smith <Morgan.J.Smith@outlook.com>]

* lisp/org/org-compat.el: Add definition of 'org-imenu-flatten'.
(org-imenu-get-tree): Use 'org-imenu-flatten'.
---

Hello!

I've been using this patch for a bit and I quite like it.  One would think
there would be an option in imenu itself to flatten trees but that does not
seem to be the case.  I copied the defcustom from 'doc-view-imenu-flatten'.

Thanks,

Morgan
