fix for #3620: basket management

- basket.pl: updating display, formatting dates,
- neworderempty: updating display, removing useless code, using ACQ framework if it exist. The ACQ framework will be used for creating items record during acquisitions. If it does not exist, default is used instead (which has many more informations, lot of them being irrelevant during acquisition, like the barcode)
- new order from imported batch: rewrite of the workflow. Now uses neworderempty and changing status of import_record to 'imported'
- s/copyrightdate/publicationyear/ as it's what libraries uses when ordering
- fixing some warnings
-
