[tasque] Close task window on ESC keypress.

[Sanford Armstrong <sharm src gnome org>]

commit 4601e927dd5eda898db12c85683e8dadb3b8ca1f

    Close task window on ESC keypress.
    
    This brings the behavior for Tasque in-line with other GNOME
    applet-style apps like Tomboy or the Hamster applet in allowing them to
    be quickly called, worked in, and then closed again.
    
    The code for the handler is pretty much straight ripped out of Tomboy,
    where I had nothing to do with writing it.
