Need to add option to set the default language for guests based on a setting not based on visitor machine

[hameedacpa]

I need to add an option to set the default language based on the setting not based on the visitors machine,

developing the board to detect the default language in case of guests is not logical and not preferable in some regions, for example in the Arab countries too many machines its default language is English but the visitors always prefer to visit the websites in Arabic

Now IPB default language always inherently obtained from the guests machine unless they set their language in Arabic ,

I hope there will be any option to set the default language for the guests from the Admin CP
