Suggestion for Login Message

For Login Message feature:

Would suggest to add an extra check to login_message filter and only output the message during normal login dialog, not when requesting a password change or when confirming a new password or when logging out.

Something similar to this:

if ( empty( $_GET['action'] ) && empty( $_GET['checkemail'] ) && empty( $_GET['loggedout'] ) ) {
    $message .= ...

Also would suggest to add an additional classname for custom styling when required, similar to this:

    $message .= '<p class="message rda-login-message">' ...

Thanks for great plugin.
