[Emacs] Evil visual line movement in markdown and org

Markdown and org files can contain long files that span several visual
lines. Moving with `evil-next-line' and `evil-previous-line' is not
exactly comfortable when that’s the case. `evil-next-visual-line' and
`evil-previous-visual-line' come to the rescue!
