F....., stupid C++.

Guess what, a simple inclusion error. I added some code to
projectcontroller.cpp which used the ->extension<IProjectFileManager*>()
and projectcontroller.cpp include project.h. It doesn't include
iprojectfilemanager.h. 

For whatever reasons this leads to project.cpp not getting the
qt_extension<> function in its code unit and thus the failing
extension() call when loading a project.

Adding an include for iprojectfilemanger.h in projectcontroller.cpp
before the project.h include helped.

So my conclusion: inlcude headers for extension interfaces before as
early as possible.

Andreas, who just wasted 1 night of coding for this stupid stuff
