Clear cache automatically on manager page reload when pub_date or unpub_date are reached.

Hello,

I was surprised to see that we need to manually clear MODX cache in order to see the publications status updated if we use pub_date and unpub_date fields.
I write a little plugin that handle this and I would like to put it there for those who want this behavior too.

What the script does :
If pub_date or unpub_date are set, we check if the date/time is reached, if so, we clear the cache part related, then we reload the current resource.

Create a plugin "ClearCacheOnPubDate" that fires on the OnDocFormPrerender event :
```
<?php
if ($mode === 'upd') {
    $refreshNeeded = false;

    foreach(array('pub_date', 'unpub_date') as $field) {
        if ($resource->get($field)) {
            if (strtotime($resource->get($field)) < time()) { $refreshNeeded = true; }
        }
    }

    if ($refreshNeeded) {
        $modx->cacheManager->refresh(array(
          'auto_publish' => array('contexts' => $resource->get('context_key'))
        ));
        $modx->sendRedirect(MODX_MANAGER_URL . '?a=resource/update&parent=' . $resource->get('parent') . '&id=' . $id);
    }
}

unset($refreshNeeded);
```
Hope this will help.
