Failure getting more than the first available remote extension from civicrm.org/extdir

CiviCRM sites Manage Extensions page will only display the FIRST available extension when retrieving from civicrm.org/extdir.

The problem is in CRM_Core_Extensions::grabRemoteKeyList() function
On line 715 - we are splitting the retrieved HTML on line feed. However the repositoryUrl output (from http://civicrm.org/extdir/ver=4.2|cms=Drupal/ (for example)) uses HTML list elements - so only a single line is present. Hence, $lines array as one item and only first extension is parsed into $exts.

We can explode on '<li>' and unset first item in resulting array. But then the preg_match on line 718 fails and I couldn't quite figure out the fix for that
