The Debugger, cmake and Qt4 plugin all need it. More refactoring to it
coming.

And there seems to be no value in the code anyway.

Rename (Q)MakeBuildStepFactory to (Q)MakeStepFacotry
Move the factories to the same files as (Q)MakeStep
Delete the old qmakebuildstepfactory.(h|cpp)

We used to build a helper library as part of the project. First with the
qmake -after SOURCES= stuff and after until now with the
gdbmacrosbuildstep. Now, the all new and fancy integretation directtly
into the qt version dialog. You build the debugger library once for
each qt version and then it's there ready to be loaded into each
project build against that qt version. Saves a lot of time.
And makes it possible to also load that library into while debuggign a
cmake project. (Need to hook that up now.)
Unfourtanetly this breaks the custom dumpers if you use a custom run
executable.

Details:  This enables us to parse the build errors correctly.
          The makesteps of the qt4project and cmakeproject have some
          code dupliaction, which could be refactored. And the code
          to find out the correct build parser could probably also
          be done better, but we are now parsing the build output for
          cmake.

replace ExtensionSystem::PluginManager::instance()->getObject<Core::ICore>() by Core::ICore::instance()

Details:  ProFileCache be gone, as is ManagedProFile, not to be missed.
Drastically simplified how ownership works.
