commit dd10aab53a3fde04f05fe6399496b36e625b4c37

    Balance ENTER with a LEAVE for all exit points.
    
    For xaccLotFill and xaccLotScrubDoubleBalance, anyway.

    Divide the value by the rate to get the amount.
    
    Avoids overflowing the amount and is anyway much more realistic:
    Value = Amount * price, so a large "rate" means a small price. Since
    get_random_rate() is biased to producing large rates (denom is fixed
    at 100), it was effectively testing infinitesimal prices.

commit bad092a46d61c5e5910a4707ed38d40883751bd9

    Prevent assigning capital gains splits to lots.
    
    They're generated by lots, and when xaccSplitComputeCapGains sees one it grabs the originating lot which naturally doesn't balance.
