Redefine the view acq.fund_debit_total:

Redefine the view acq.fund_debit_total:

1. Correct the mistaken use of acq.fund_debit.id for fund,
instead of acq.fund_debit.fund.

2. Join to acq.fund so that we get a zero total for a fund
with no debits in acq.fund_debit.

Four other views are affected indirectly because they are defined
in terms of acq.fund_debit_total:

	fund_encumbrance_total
	fund_spent_total
	fund_spent_balance
	fund_combined_balance
