[imp] using a user pref to set a value in conf.php

[Liam Hoekenga]

Our antispam solution has two classes of users.  People who can "train" their
spam filters,  and people who have a "generic" set of filters.  I've created a
horde pref "spam_trainer", and I'd like to be able to determine the behavior of
the spam reporting links based on whether this preference is set or not.

So.... I guess the question is, how to get access to the preferences scope
inside of config/conf.php?
