soft wrapping text buffers

I've not been using emacs much for a while so forgot how to soft wrap long lines in text-ish files. Turns out it's still kind of a hack, that just dynamically fiddles the margins. Still, works OK.

(global-visual-line-mode t)
(use-package visual-fill-column :ensure t
  :init
  (setq visual-fill-column-center-text t))
