Bug 10535: by default sort funds by name

In parcels.pl, and other acquisition pages, the funds are not sorted
by name in combo-box.  With a great number of funds, it is difficult
to find one.

This patch adds a default value to $orderby arg of C4::Budgets::GetBudgets.

Test plan :
- Create a new fund with a name beginning with 'z' and set you as owner.
- Create a new fund with a name beginning with 'a' and set you as owner.
- Go to a vendor and click "Receive shipments"
- Look at fund combobox
=> Funds are sorted by name

Passes all tests and QA script.
When testing make sure your funds would sort the other way
around when sorting by code instead of description.
