lang/org: major refactor & add org-fancy-priorities package

- Fixes an issue where evil bindings weren't working in org-mode
- Significantly slims down on unnecessary keybinds
- Remove +org-init-keybinds-for-evil-h hook and reli more on our new
  evil-org fork, which has upstreamed some of our changes.
- Documents undocumented functions, remove unnused ones, and reorganize
  org's autoload libraries by convention.
- Adds org-fancy-priorities for more elegant (and subtle) priority
  display than ugly [#A] tags.
