bug & fix: empty order notifications

hello, since the upadate to 2.0.6 i receive empty order notification emails. the email to the client works without a problem. i've looked into the code and found the bug.

marketpress.php line 3386: someone forgot the chaining dot before the equal sign. this way the message is always overwritten. to fix it:

replace this:

$msg = sprintf($msg, $order->mp_shipping_info['email'], admin_url('edit.php?post_type=product&page=marketpress-orders&order_id=') . $order->ID);

with that:

$msg .= sprintf($msg, $order->mp_shipping_info['email'], admin_url('edit.php?post_type=product&page=marketpress-orders&order_id=') . $order->ID);

could you please release a new version as quick as possible?
