Allow the minimum 'view in admin' role of 'list_roles' to be filtered

[baden03]

Just because a user can list_roles does not mean they need to have the Members menu item added to their admin. For example, if we want to allow a manager to promote an employee to become a manager they need the ability to list_roles but do not need to have the Members menu added to their admin interface.

usage:

// Only show members manager in admin to admins.
add_filter( 'members_min_show_admin_role', 'show_role_manager' );
function show_role_manager( $edit_roles_cap ){
    return 'edit_roles';
}

Thanks @baden03 - would you mind changing the hook name to members_show_roles_page_cap? Thanks!
