Bug 8892 fix Plack scoping in acquisition

basket.pl has a local sub get_order_infos that require our-ing the
basketno variable.

but I couldn't be sure it is, so I just switched basketno to "our"

neworderempty.pl has 2 local sub that require our-ing some variables:
subs MARCfindbreeding and Load_Duplicate
