Bug 7254 Show pending orders from baskets with closedate > 180 days

Current code for selecting pending orders does not select orders from baskets
with a closedate > 180 days.
The code in Acquisition.pm already includes a FIXME for that.
IMHO this part of the where clause should just be removed; an order is pending
until it is filled. If you do not want to fill it, delete it.
