#673 Transactions view - Modify historic for a value

[m_legrand]

- Complex operations
- Just only change quantity, debit, credit and expense
- Just also only remove or add a line
- UPP is not the same when sell and buy or buy and sell for a quote in a same day. Must to include hour transaction.
- Actually, modify a line give curious results in matrix and portfolio views. Must to restart iTrade to have real UPP
In that example in attached file, UPP is not the same and it's false
Modify quantity of last line does'nt modify the first UPP

UPP don't change after modification
