Description:
------------
imap_fetch_overview() ignores the order of integers in the sequence-field. this is annoying when you try to sort mails
and then fetch a sorted list.

Reproduce code:
---------------
$res=imap_fetch_overview($mbox,"1,2,3,10",0);
OR
$res=imap_fetch_overview($mbox,"10,3,1,2",0);
OR SO ON ...

Expected result:
----------------
$res[0]->msgno=10
$res[1]->msgno=3
$res[2]->msgno=1
$res[3]->msgno=2

Actual result:
--------------
$res[0]->msgno=1
$res[1]->msgno=2
$res[2]->msgno=3
$res[3]->msgno=10
