9.1 Proposal: shutdown menu

[pgf at laptop.org]

this feature has been discussed on the list(s) earlier, but i'm not
sure of its status.  i'd like to make sure it gets on the table.
(and it just came up in dan's ethiopian report.)

currently it is much easier to "crash" the laptop (by holding the
power button down) than it is to shut it down cleanly.  while the
journalled filesystem (currently) can recover from this on the
next boot, application writes in progress might not.

pushing the power button on the laptop should present a menu or dialog
allowing shutdown.  as a strawman UI, the pushing the button should
result in a simple dialog that looks like:

        The laptop will suspend in 5 seconds.
           Shutdown | Suspend Now | Cancel

(this will need to interact with lid-close in a sensible manner.)
