[O] APPT_WARNTIME not honored anymore in 8.0

[Ivan Kanis]

Hi,

Suppose I have the following entry:

** Karaoke <2012-09-21 Fri 20:00 +1w>
   :PROPERTIES:
   :APPT_WARNTIME: 17
   :END:

I should get a notice 17mn before 20:00 that I need to go to karaoke.
Now it does the default 90mn. It's a regression.

I might have time next week to look into it.
