Bug 24347: (follow-up) Remove custom catalog search from acquisitions

This patch removes the "neworderbiblio" script and template which are
made obsolete by the "search to order" feature.

deleted:    acqui/neworderbiblio.pl
deleted:    koha-tmpl/intranet-tmpl/prog/en/modules/acqui/neworderbiblio.tt

Some documentation in addorder.pl has been corrected to remove reference
to neworderbiblio.pl.

To test, apply the patch and verify that the correct files have been
removed.

Search the Koha codebase to verify that no links to
acqui/neworderbiblio.pl remain.
