Gideon requirements

[Harald Fernengel]

Hi,

I just noticed that editorproxy needs the markinterfaceextension which only 
exists in CVS HEAD.

Since I hoped I could keep my stable KDE 3.0.x for a while, I've #ifdef'ed it 
out and completely broke the nice new debugging stuff, but at least I can 
work on the other plugins.

The question now is: Should we keep 3.0 compatibility or do we require KDELibs 
HEAD?

Best regards,
Harry
