Accounting Ledgers; drilldown form updated to better handle Loans with no Maturity Date

In the Accounting Ledger drilldown form, if an Account does not define a Maturity Date, as in a Revolving Credit Loan, the First Date and Number of Periods are blanked when the Opening Date or Frequency fields are changed. Begin Date is now updated based upon the Opening Date and Frequency.

In addition, if the Opening Date if after the Maturity Date the First Date is now updated based upon the Frequency.
