Added msg.user_info[:lang] and its alias msg.lang / msg.lang= which are used as the definition of the user's prefered language. The default is 'en'.
Set the default refreshAfter time to 200ms, because 1s was too laggy. 200ms feels as fast as it should, and if you have some highly interactive dependencies on text control input, just set it to something even lower.
Enabled support for localized.yaml, strings.yaml and associated methods. The localized_string uses the msg.lang to get the desired language and it's by default included in gui_params for GUIPlugin. You can use it for other plugins too by including Localization.
