Re: [PATCH] org-id: allow using parent's existing id in links to headlines

[Rick Lupton]

Here's an updated patch, which adds (optional) search strings to ID links, and 
the option to inherit ID targets from parent headline / the top level file 
properties.  I've also updated ORG-NEWS and the manual, and added tests.

I think I've fixed all the issues with my first patch about which headline gets 
used for the description when inheriting IDs, what happens if there is no ID, 
etc.

I've also moved the org-id specific logic from `org-store-link` to 
`org-id-store-link`, and added the `interactive?` argument to link store 
functions as discussed.

The default value for the new option `org-id-link-use-context` is `t`, but it 
can be set to `nil` (or disabled with a prefix argument to `org-store-link` 
temporarily).  This is a change in default behaviour when storing ID links with 
point at a subheading, named block, or target, or with an active region.

The option `org-id-link-consider-parent-id` I've left with a default value of 
`nil`, since I'm not sure if everyone will want this behaviour.

Thanks
