[Enhancement] Add filter to menu link

Hello Frank,

Thanks for the plugin, I am a first time user and playing with it a little bit ??

I wanted to add a suggestion:
it would be nice to add a filter inglmb-frontend.php lines 74 and 75:

$logout = '<li class="menu-item logout"><a href="'.wp_logout_url( home_url() ).'" title="Logout">Log out</a></li>';
    $login  = '<li class="menu-item login"><a href="' . get_the_permalink() . '/#login" title="Login">Log in</a></li>';

    if(has_filter('wpstudio_add_logout_filter')) {
        $logout = apply_filters('wpstudio_add_logout_filter', $logout);
    }

    if(has_filter('wpstudio_add_login_filter')) {
        $login = apply_filters('wpstudio_add_login_filter', $login);
    }

So that we can customize classes for example in our theme functions.php

function wpstudio_add_logout_classes($logout) {
	$extra_classes = 'right';
	$logout = '<li class="menu-item logout '.$extra_classes.'"><a href="'.wp_logout_url( home_url() ).'" title="Logout">Log out</a></li>';

	return $logout;
}
add_filter('wpstudio_add_logout_filter', 'wpstudio_add_logout_classes');

What do you think? To messy?
