Title: New option show_default_text_always (always show multiselect default text) 

This option says to the Choosen "Do not hide Default Text in multiselect mode, keep it visible for user".
Some users do not realize that you need to click the component to select additional options.
So the text helps them understand it.
By default show_default_text_always = false and The Chosen acts as usual.
