my-org: enable shell mode for org-babel
snippets: add $n (notes) for org-mode
snippets: make web-mode include html mode

Yasnippet does ship a bunch of templates for html.
init.el: if->when
init.el: clean-up my emacs-lisp-mode hooks.
init.el: disable my insert-my-name keystroke

It's stamping on other keystokes and I suspect I could just use
something else.
init.el: swap around the various expansion options

Also:
  * don't stomp ac-menu-map
  * enable AC in org-mode
my-org.el: fix setup of babel

I didn't mean to disable elisp-mode!
snippets: add tested-by snippet to message-mode
snippets: move git-tag related snippets to git-commit-mode

Also:
  * add .yas-parents to it from message-mode, magit-log-edit-mode
snippets: add $s -> #begin_src expansion for org-mode
