-cleanup the toplevel CMakeLists.txt a bit

-remove include_directories( CMAKE_CURRENT_SOURCE_DIR CMAKE_CURRENT_BINARY_DIR)
in the subdirs, since this is done now automatically by cmake (the CMAKE_INCLUDE_CURRENT_DIR option
-include_directories(KDE4_INCLUDES) in the toplevel CMakeLists.txt, so it
doesn't have to be done in every subdir
