Load password-strength-meter only on needed pages.

Cause it loads on all of them. It sure does not help in decreasing load time. So I’ve thought to help some people who may be into the user experience thing.
In plugings/s2member/includes/classes/css-js-themes.inc.php ( Line:83 & 87 )
before

wp_enqueue_script ("ws-plugin--membership", $s2o . "?membership_js_w_globals=" . urlencode ($md5) . "&qcABC=1", array ("jquery", "password-strength-meter"), c_membership_utilities::ver_checksum ());

and

wp_enqueue_script ("ws-plugin--membership", $s2o . "?membership_js_w_globals=1&qcABC=1", array ("jquery", "password-strength-meter"), c_membership_utilities::ver_checksum ());

add :

if( $hook != 'users.php' && $hook != 'wp-login.php' ) return;

or your own custom .php file. I just did an example.
Done. Now one thing less to worry about.

Otherwise. Great work the plugin!
