Bug 5701: Distinction between authors/additional authors in staff normal view (MARC21/XSLT)

At this time all entries in 100/110/111 and 700/710/711 are shown together.
We want to see the difference between an author and an added entry. (The 700
author could for instance be an illustrator.)
To this end we like to see the eventual relator code or term in $4 or $e too
(displayed between brackets after the name).

In the patch the code for authors is moved to a template routine at the end of
the xslt stylesheet.
