Support for user-extensible speed commands.

* lisp/org.el (org-speed-command-hook): New. Hook for installing
additional speed commands. Use this for enabling speed commands on
src blocks.
(org-speed-command-default-hook): The default hook for
org-speed-command-hook. Factored out from org-self-insert-command
and mimics existing behaviour.
(org-self-insert-command): Modified to use org-speed-command-hook.
