commit d4bbede08f171211fd1dd3d6018c8f95dca86f34
Author: Mike Alexander <mta at umich.edu>

    Set val_imbalance in gnc_transaction_balance_trading.
    
    When the code was refactored in 61973a8 the return value from the new
    function gnc_transaction_get_commodity_imbalance was ignored.  This had
    the effect of using an uninitialized variable to set the value in a new
    trading account split that is not for the transaction's currency.  That
    means that multicommodity transactions created with this bug and trading
    accounts on will not be balanced.

    Remove the code in on_matcher_ok_clicked that builds refs_list.
    
    The use and release of refs_list was removed 7358bcc in August 2012 and
    since then on_matcher_ok_clicked has been leaking a GSList on every call.
