[IPython-dev] Displayhook configuration (Walter take heed!)

I guess it's time to implement configurable display hooks.
I think the most lightweight chain-of-command implemention would be:
- Rewrite Prompts.py/CachedOutput._display() to do:
for displayer in ip_display_hooks():
- Move current CachedOutput._display to another class Default
ip_display_hooks() return the list with the current display hook as
the last item. It's also the "public api" for setting display hooks -
people just prepend their own display hooks by doing
(other places than 0 are legal too if the user thinks he knows what he's doing)
The fictional PipePrinter would check if it is of the wanted type, and
raise TryNextHook if not (or if the processing is only partial).
I could do this, but since Walter asked for this he might be the one
to give it a shot?
