Nicer display when using a link, (particularly EBDB links) for the DELEGATED_TO property

[nickgarber]

At present it shows the whole raw text value.

Ideally, I'd like for it to either display

1. the link's description (probably most straight-forward)
2. or alternatively, some value at the dereferenced link

Many thanks!

The DELEGATED_TO property is displayed in the agenda using package org-agenda-property. It hasn't received updates recently but provides nice functionality.

As an initial step, I'll look to see what it'd take to make it display an org-link's description.
