[PATCH] emacs: notmuch-hello: Make widget-keymap a parent of notmuch-hello-keymap

[Nelson Elhage]

This lets us pick up later changes to widget-keymap if the user
customizes it in some way. This is the recommended way to use
`widget-keymap', according to its help.

This goes on top of Sebastian's patch. See
id:1273805175-6660-1-git-send-email-nelhage at ksplice.com, where I
submitted a similar, but less thorough, patch as his.
