#10 Day labels on expense report wrong when date not in ISO format

[urugamai]

bug in day labels of expense report when using dmy date format. Lines 112 - 114 of '.../expenseheaders/report/PrintCommonFunctions.php' could be changed as follows to fix this issue:

$isodate = tesAddDate($EH['weekenddate'], -$i);^M
$date = cvtDateIso2Dsp($isodate, $dateFormat);^M
$str .= "" . changeLiteral(Date2Day($isodate)) . "

---

$date";^M

Since the code didnt format well, here is a patch.
