:store for new link model

[John Kitchin <jkitchin@andrew.cmu.edu>]

I was looking through all the changes needed to centralize the link code
we have been discussing.

One point we didn't discuss yet is the org-store-link-functions.

These could be stored in a :store property in `org-link-parameters'.
Instead of a variable for org-store-link-functions we could generate it
on demand from org-link-parameters.

Changing this isn't difficult, we just remove the add-hook lines below,
and add :store 'func to the link definition. Right now, I expect this
will look something like this:

(org-add-link-type "bbdb" 'org-bbdb-open 'org-bbdb-export :store 'org-bbdb-store-link)

I listed the places impacted by this below. As you can see, some are
"core" and some are "contrib". Is there a protocol for modifying the
contrib code? 

While thinking about this, would it be desirable for each of these
changes to each file be a separate commit?

Thanks,
