Issue 868 🚸 add email trackers and sort files

[thomasmerz]

This PR solves issue #868. I only changed files where link.getmailspring.com has already been included so only 4 trackers have been added to each file.

⚠️ Please check carefully because I let vim sort by '<,'>sort " which changed many, many lines: 👁️ @notracking
