3.1.0 Wordpress plugin using the Onelogin PHP Toolkit

• Multisite improvement. Now when multisite is enabled, on the "Network Admin" dashboard appears a "Network SAML Settings" where you can define a SAML template setting, and then inject it in sites. Also will allow you enable/disable multiple sites on a unique view.
• Now the onelogin_saml_keep_local_login will also hide the login form on wp-login.php view. So when on a logout action, we can notify the user with the typical message of 'You are now logged out.' without showing the local login form.
• Update php-saml to 3.3.1
• Update xmlseclibs to 3.0.4
