Well, you don't need to know the implementation of writeConfig, you just
need to know wether you want to store the information of the items to
the config yourself or just do something not that intrusive.

Adam surely tested that his changes worked in kdevelop ;) But I do
understand the problem. So as I said, as long as you make the
read/writeConfig and set/useDefaults methods virtual so they can be
changed completely in subclasses its fine with me reverting the changes.
