Same-day range export generates empty dataset (fix provided)

If you set the export range to the same day, you can an empty dataset because the SELECT statement will look for a range spanning a single second of the day.

Line 128 of download_count/includes/download_count.export.inc

$from = strtotime($start['year'] . '-' . $start['month'] . '-' . $start['day']);
$to = strtotime($end['year'] . '-' . $end['month'] . '-' . $end['day']);

below this, add the following conditional:

$from = strtotime($start['year'] . '-' . $start['month'] . '-' . $start['day']);
$to = strtotime($end['year'] . '-' . $end['month'] . '-' . $end['day']);
if ($from == $to) {
$to += 86400;
}

Which means: If the start and end time stamps are the same, make the end time stamp 24 hours after the start time stamp.

I believe this provides expected behavior.
