#13 Add time limit to promote

[Aviran Mordo]

There is a need to add a time limit for stories to be
promoted. For instance stories can only be promoted if
they have being submitted within the last 2 days, or
the last 24 hours.

The Fix:
In config.php:
add the folowing line -
define('days_to_publish', 2); // After this many days posts
will not get published

In link.php change the function: function insert_vote as
follow -

the if statement if($this->status == 'queued' &&
$this->votes>=votes_to_publish) { ...

should be -
if($this->status == 'queued' &&
$this->votes>=votes_to_publish) {
$now = time();
$diff=$now-$this->date;
$days=intval($diff/86400);
if ($days <=days_to_publish) {
$this->publish();
}
