Subject: Change disabled-command-function and disable commands

I want to be able to do anything, but some commands are bound to keys that I
hit all the time and it's annoying.  So I've disabled them but changed the
`disabled-key-function' to check whether I've passed the command with M-x or
using the dumb keybinding, and only allow the M-x form.
