Missing email-mark in the new writer field#185

Next to the link-mark of the new writer field, it would be great to have an email-mark. Like in the exsiting textarea. Most of the clients will surely will write the email-address without the mailto: before. And the _blank-option will be obsolete. When I see the websites of my clients, they use the email-links in inline-text often more than the website-links.

type: writer
    marks:
      - bold
      - italic
      - link
      - email

yes please!
