There were quite a few classes using CPlusPlus namespace in the
CppTools plugin. Rename them and do some other small namespace
related coding style fixups.

A manual squash/merge of the changes below, plus a couple of subsequent
code fixes.

59085aa5fbb99e2d786cd2c1a06c24a111ccb49f:
    Modify CppModel::ProjectInfo

    Adding per project node information, to pass on the correct
    defines/includes for each file, instead of aggregating them incorrectly.

    Also split up SOURCES and OBJECTIVE_SOURCES.

    Also ask the toolchain to convert the compilerflags to flags the
    codemodel understands, for now only gcc and only c++11.

    Also make the toolchain aware of the flags used to compile, so that it
    can emit the correct defines.

    Note: No header files are passed on.

74028802314cd4e75b41b46407433e07090a304d:
    GCC: Evaluate cxxflags when checking for predefined macros

ebaaa4957e4c02cc9637a998eddae1d0acd74f83:
    MSVC: Take cxxflags into account when checking for predefined macros

Now the type hierarchy widget will also show the classes
derived from the selected one. For consistency the way
the base classes are shown was changed too. The diagram
below is an example from Creator's code when openining
the type hierarchy for BaseTextEditorWidget:

Bases
 +QObject
  +QWidget
   +...
     BaseTextEditorWidget
 +QPaintDevice
  +...
    BaseTextEditorWidget
Derived
 +BaseTextEditorWidget
  +VCSBaseEditorWidget
    GitEditor
    MercurialEditor
    ...
   GLSLEditorWidget
   CppEditorWidget
   QmlJSTextEditorWidget
   ...

Depending on the project and on the selected class the
hierarchy widget might take a bit to be constructed.
This should be improved later.
