Version 1.5.3.4 with small fixes

Typemill 1.5.3.4 comes with some small fixes:

• The captcha feature has been fixed partly, so you should be able to use recaptcha again.
• The library for twig has been updated.
• Dependencies have been updated.
• Escape slashes in headlines are now stripped out from the Table of Contents.
• German translation for login error added.

There will be some small updates in the next days e.g. for the mail-plugin and the ebook plugin.

Please note that there will be only small maintenance updates for Typemill V1 in future. Typemill V1 does not run with PHP 8.1. We are working on a Version 2 for Typemill now that will support PHP 8.1 and higher. Version 2 is planned for 2023.
