    Bug 798950 - Bug Report: Incorrect Currency Conversion and Provider Invoice Payment Recording
    
    - Balancing lots always involves splits in the same account. So
      the relevant number to use in the calculations is the split
      amount, not the split value.
    - Additionally don't assume transactions are single-currency.
      So if amounts change, recalculate the associated values
      based on deduced exchange rates.
    - Finally if the lot balancing resulted in a split to be broken up
      into two splits use conservative calculations for the new
      splits' values to avoid introducing imbalances due to
      rounding errors.
