fixed budget reporting in email

The reported available rest of the budget should be calculated via an excel formula. This lead to the warning in excel, that this file was downloaded from the internet and you need to accept this warning for the calculation to happen. With this fix, the rest of the budget is directly entered into the excel sheet.
