"vTextPasswordConfirm" update

Custom error message for "vTextPasswordConfirm" was not honoured on Empty form field.

I am not sure if its correct way to do it, but it worked for me. Consider it a pull request if it makes sense.
Added Swedish translation
Update ficountryoptions.class.php

Will make it possible to translate the country listing options. This way it is based on MODX his cultureKey setting. Maybe good to add an overrule option too?

Because without this checks you will get an error when it's not an array?? But why at all?? You can only add this one to one single placeholder right? it isn't an array I guess?
Update snippet.formitisselected.php

array check on $input to remove php warning notice
