Remove org-agenda stuff

I never really ended up using it, perhaps I will revisit it at some
point but for know there is no need.

-** Agenda
-
-   Set up a keybinding for [[help:org-agenda][org-agenda]] and tell it where to look. I
-   have a bunch of org documents making up a sort of wiki which I keep

-   I often want to see TODO items that aren't scheduled to decide on

-   By default, the agenda clobbers the rest of the windows in the

-   controlled by [[help:org-agenda-window-setup][org-agenda-window-setup]].

-** Archival
-   It's nice to be able to clear out old and irrelevant things from
-   task lists, etc. To that end, [[help:org-archive-subtree][org-archive-subtree]] is very nice. To
-   configure where archived items go, we can set [[help:org-archive-location][org-archive-location]]:

-
-   The =datetree= bit there is a special option that means archived
-   items will be grouped by the date they were marked =DONE=, or the
-   date they were archived, if that's missing.

   Org is better suited as scratch space than Funamental, I'd say.
