Title: [WO-358] Do no use quotes with mime-word encoded address names

If the name part of an address consists only ascii letters and numbers, the name is kept as is. If the name includes printable punctuation marks, the name is surrounded with quotes. If the name includes non printable or non ascii characters, it is encoded to mime word.
