CMakePM: Proper support for Unity builds

Browse Source 
A Unity build can be enabled by specifying CMAKE_UNITY_BUILD set to ON
globally or per target bases via the UNITY_BUILD property.

CMake would then add unity_NN_[cxx|c].[cxx|c] sources files that would
include the existing project files.

The existing project files would then be added as "headers" to the
project and exported via the CMake file-api.

This patch makes sure that these new "headers" are added to the Qt
Creator's code model and have proper syntax highlighting, be available
to plugins (e.g. Todo) and so on.
