Please find attached a first version of a patch adding support for IDs
as remember targets.

This patch adds support for specifying the ID of a target headline.

Open issues:
* Using a cons cell seems a bit ugly.  A string would be fine too but
  this is already used by the headline itself in the choice element.
* The visual appearance of the ID choice is suboptimal.  Is there any
  way to hide the const visually?
* The comments in the remember buffer seems to be setup wrong, where
  must I hook in to support IDs there?
