file_get_contents and some hosts

FYI, some hosts (incluing 1&1 and Dreamhost) disable the ability to use file_get_contents on a URL, which effectively stops Facebook Status from working. After some playing around, I was able to get it working using cUrl.

Essentially, I turned this:

	  if (!$rss = file_get_contents($statusurl)) {
		watchdog('fbstatus', 'Could not fetch via file_get_contents '. $statusurl);
		return '';
	  }
<code>

Into this:
<code>
    if (function_exists('curl_init')) {
      $ch = curl_init($statusurl);
      curl_setopt($ch, CURLOPT_VERBOSE, 1);
	  curl_setopt($ch, CURLOPT_URL, $statusurl); 
	  curl_setopt($ch, CURLOPT_TIMEOUT, 60);
	  curl_setopt($ch, CURLE_OPERATION_TIMEOUTED, 30);
	  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
	  curl_setopt($ch, CURLOPT_USERAGENT, 'Firefox');
	  if (!$rss = curl_exec($ch)) {
		$curlInfo = curl_getinfo ($ch);
		$curlError = curl_error($ch);
		watchdog('fbstatus', 'Could not fetch via curl '. $statusurl .': '. $curlInfo .', '. $curlError);
		return '';
	  }
    }
    else {
	  if (!$rss = file_get_contents($statusurl)) {
		watchdog('fbstatus', 'Could not fetch via file_get_contents '. $statusurl);
		return '';
	  }
    }

It took some playing around with it, so it probably uses more options than absolutely necessary.

On a separate note, it's worth noting that SimpleXML isn't available in all environments (particularly for PHP 4), so you should probably list that in the requirements.
