[net-charts] modify process-datelist to use account-balances

Browse Source 
This will retrieve the cached balances in account-balances, rather
than calling (gnc:account-get-comm-balance-interval)
or (gnc:account-get-comm-balance-at-date) which are very expensive
because they will call xaccAccountGetBalanceAsOfDate which will scan
the account splitlist every time.
