Long is the road to MARC..

Not related to MARC :
* removed HLT- empty link when no basket for a supplier (should be useful to copy this into rel-1-2 i think)
* fixed some "use of uninitialized value"
related to MARC
* changed use Acquisition to use Catalogue, new package for MARC management

For instance, nothing is done to MARC DB, but structure is modified (see Biblio.pm for details), and everything seems to work : it's still possible to use acqui, and it fills old-DB pretty good.

WARNING : if you work on main trunk, please note Acquisition.pm is NO MORE USED in /acqui/ system. Every sub in Acquisition.pm has been moved to Biblio.pm or Catalogue.pm.
