added array and array count validation

added validate_array/count/countmin/countmax/countbetween -
corresponding replace_count/countmin/countmax/countbetween message
functions - corresponding validator error messages into all language
files (please have maintainers update their language files) - also
converted spaces to tabs in the polish language file to fit all the
others.
