Drupal 7 port

Very useful tool.

To get this to work for drupal 7 I changed these two lines in features_clone.class.inc;

$sql = "select filename from {system} where name='%s' and status=1";
$modulefile = db_result(db_query_range($sql, $this->src_feature, 0, 1));

to

$sql = "select filename from {system} where name=:name and status=:status";
$modulefile = db_query($sql, array('name' => $this->src_feature, 'status' => 1))->fetchField();

The clone seems to work but then you get a php error after the clone has finished;

PHP Fatal error: Call to undefined function module_exists() in ***/includes/cache.inc on line 170
Drush command terminated abnormally due to an unrecoverable error. [error]
Error: Call to undefined function module_exists() in ***/includes/cache.inc, line 170

I don't know if this has an impact on anything because the clone still took place.
