After all I don't need all that stuff in the cmakeplugin, all i needed
is now bundled in debugginghelper.h/cpp

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

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

It was missing for CustomExecutableRunConfiguration and
Qt4RunConfiguration.

Was a bit confusing that a MakeStep was constructed by a
MakeBuildStepFactory and configured by a MakeBuildStepConfigWidget.

The MakeStep of the generic project manager was renamed to
GenericMakeStep.

Details:  Move that code from qt4project to a common class.

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.

Details:  These classes replace a number of classes with differing
interfaces by just one class. The design isn't quite perfect, but a lot
better than what it used to be. Also moved the ToolChain classes to the
projectexplorerm so that eventually the cmake plugin can also use them.
