v1.4.2

• If a mail contains several spam headers, the information is no longer displayed twice in the detail dialog. (by @vali-um in #48)
• The add-on is now also available for Thunderbird 115.* (the spam column is not functional, only the detailed information of the spam rules). (#59)
• If a mail does not contain a spam header, the details button now shows "No Spam Score" and no longer the value of the previously selected mail. (by @vali-um in #60)
