Per-user preference: "mark post as read when emailed"

[LeoMcA (Leo McArdle)]

Plugin created:

Mark post as read on email

Once installed, when users head to the email section of their preferences, they should see a new preference: [Mark posts as read when I'm emailed about them] Enabling this means that whenever they’re emailed about a post, Discourse will mark the post as read on the website, ensuring their notifications don’t get cluttered up.
