big change from Katipo.

big change from Katipo.
------------------------------
- Results for 'mutli orders with matching titles attached to same bibitem'  now split into new .tmpl file, "acquire-multi-order.tmpl".
- this script/tmpl does 3 things!?!, pulled search results out of acquire.pl, now points to searchresults.tmpl.
- little fix to display correct supplier info in acquire.pl's 'detail' view.
- Little fix on previous commit, now doesnt break single order acquire view.
- Fix for RT:698 https://staff.katipo.co.nz/rt/Ticket/Display.html?id=698.
- now display correct supplier title when 0 results returned.
- Now pickes up basketno, to display as url to tmpl.
- Adding in fix for bibitems with more than one matching order.
- Rolled back to prod version, added 'create new bib-group' fix.
- Mason's ACQ fixes from HLT-DEV , work in progress
- Now does a lookup in aqorders, for all existing orders matching  biblioitems, then presents all matching orders in a table. this feature can be overridden by calling acquire.pl with multiorderseach=n in url, acquire.pl will instead go to specific order.
- Now catches, and returns to acquire.pl if newitems() fails.
- Now takes a barcodeerror value as arg.
- 'create new biblioitems' checkbox now only apears for bibitems with >= 1 items attached.
- adding stuff to let hlt have an accession date link from moredetail.tmpl
  that actually does something other than break biblioitems - not working yet
- Added output for volume as well as volumeddesc
- Added volume description to output loop
- Making change for bug #3676 displaying date unformatted
- More bugfixing this time a bug not saving volume info
- Fix for bug 3529, allow freight to be distributed among the items
- added a sprintf to get the number displaying in normal notation
- Altered the auto_barcode to actually get something other than 1
  but now got a problem with the result displaying in scientific notation
