Prune out unused org-mode features

It was indeed funny to read the bit in the agenda config.

-** Workflow States
-   I like to have =IN-PROGRESS= and =CANCELLED= workflow states as
-   well as the standard =TODO= and =DONE=. Cancelled items also want a
-   note attached explaining why. All this can be added by setting
-   [[help:org-todo-keywords][org-todo-keywords]]:
-
-   #+begin_src emacs-lisp
-     (setq org-todo-keywords
-           '((sequence "TODO" "IN-PROGRESS" "|" "DONE" "CANCELLED(@)")))
-   #+end_src
-
-   The ="|"= separates /needs further action/ states (before it) from
-   /no further action needed/ states (after it).
-
-   I also want to log the date and time when a note is marked as done:
-
-   #+begin_src emacs-lisp
-     (setq org-log-done 'time)
-   #+end_src
-
-** Agenda
-   Time to try org-mode's agenda feature again I think. Last time I
-   didn't end up using it much, but I am /much/ more of an Emacs
-   addict now so I do forsee it actually surviving (this will be funny
-   to read in the future if not).
-
-   I want to show all TODOs in =.org= files under my top-level
-   =~/Documents/org= directory and any in this config itself. This is
-   done by enumerating all files under =~/Documents/org= with
-   [[help:directory-files-recursively][directory-files-recursively]], then setting [[help:org-agenda-files][org-agenda-files]] to this,
-   along with this config's path.
-
-   #+begin_src emacs-lisp
-     (let ((org-docs
-            (directory-files-recursively "~/Documents/org" ".+\.org$")))
-       (setq org-agenda-files `("~/.emacs.d/config.org" ,@org-docs)))
-   #+end_src
-
-   Also I find it really very annoying that the the current window
-   layout is destroyed when you run =org-agenda=. That behaviour is
-   changed by setting [[help:org-agenda-window-setup][org-agenda-window-setup]]:
-
-   #+begin_src emacs-lisp
-     (setq org-agenda-window-setup 'current-window)
-   #+end_src
-
-   Include events from my diary:
-
-   #+begin_src emacs-lisp
-     (setq org-agenda-include-diary t)
-   #+end_src
-
-   Though I don't like the time grid being on by default.
-
-   #+begin_src emacs-lisp
-     (setq org-agenda-use-time-grid nil)
-   #+end_src
-
-   I primarily use the TODO list to keep track of un-scheduled tasks,
-   so I don't want those displayed in there:
-
-   #+begin_src emacs-lisp
-     (setq org-agenda-todo-ignore-scheduled t)
-   #+end_src
-
-   Finally, I want a keybinding for the weekly agenda and global TODO
-   list agenda view:
-
-   #+begin_src emacs-lisp
-     (defun org-weekly-agenda-and-todo-list ()
-       (interactive)
-       (org-agenda nil "n"))
-
-     (global-set-key (kbd "C-c a") 'org-weekly-agenda-and-todo-list)
-   #+end_src
-
-** Habits
-   Habit tracking requires the habits org module to be loaded. This is
-   done by adding the symbol ~'habits~ to [[help:org-modules][org-modules]], if it's not in
-   there already. I originally didn't have the surrounding ~unless~,
-   but it causes problems when re-loading the config using
-   [[help:org-babel-load-file][org-babel-load-file]].
-
-   #+begin_src emacs-lisp
-     (unless (member 'habits org-modules)
-       (add-to-list 'org-modules 'org-habit)
-       (org-load-modules-maybe t))
-   #+end_src
-
-   The [[help:org-load-modules-maybe][org-load-modules-maybe]] call forces org to load the modules in
-   [[help:org-modules][org-modules]]. Not sure it's needed, but I ran into some weird issues
-   and I think it fixed them.
-
-   The consistency graph is very nice but overlaps a lot of the habit
-   names, so I want to move it to the right a little:
-
-   #+begin_src emacs-lisp
-     (setq org-habit-graph-column 42)
-   #+end_src
-
-   Also it displays days that you did a habit in red if the habit was
-   overdue on that day, which makes a sort of sense, but always
-   showing days you did things in green makes more sense to me. The
-   variable [[help:org-habit-show-done-always-green][org-habit-show-done-always-green]] controls this.
-
-   #+begin_src emacs-lisp
-     (setq org-habit-show-done-always-green t)
-   #+end_src

 ** Identation
    Setting [[help:org-adapt-indentation][org-adapt-indentation]] to ~t~ ensures that Org will indent text
    under a headline:
