appt-display-format has bad Customize default and no value menu

[Drew Adams]

I don't use appt.el anymore, but I ran across this while testing
something else.

emacs -Q

M-x load-library appt

M-x customize-variable appt-display-format

The standard value is `ignore', and this is a mismatch (`ignore' is
not a valid value). No value menu is available to pick a value.
