    Mortgage Assistant: Handle daily payments
    
    That case was left out of the payments-per-year calculation.

commit 889a4dde956d623ed184fd9b1ce97e96d2998f66

    Mortgage assistant: Avoid crash when returning to the repayment page.
    
    And as a side benefit don't leak signal handlers for the repGncFreq
    changed signal.
    
    The crash occured because gnc_frequency_setup_recurrence first calls
    gnc_date_edit_set_gdate which emits a changed signal that, if it
    wasn't the first call to loan_rep_prep would call
    update_repayment_formula_cb and that would generate a new recurrences
    list. But the still running gnc_frequency_setup_recurrence still had a
    pointer to the old list and when it tried to manipulate it it would
    crash.
    
    This change disconnects the previous signal handler preventing the
    list from being replaced.
