Adds org-habit.
Changes function open-init().

Previously, open-init() would open my init.el. Now it opens my LOCAL
.emacs.d folder in dired. I find myself spending more time tweaking
misc.el and mode-specific.el and going through init.el just to get
dired open more easily is silly.
So much for atomic commits, just change everything.

Oops. I did a lot between commits.

- Reorganizes my collection of open-*().
- Reactivates and moves the analytic template functions, abbreviate to
- at-*().
- Creates a new section called Project functions. These start with
- proj-*. The first one is proj-ipsur, which opens dired in the ipsur folder.
Lots of changes.

- Improves README.org
- Cleans up init.el
- and tweaks mode-specific-config
