MSVC 9 compile fixes and cleanups

* added renamed files in revision 25337
* renamed BLI_util.h -> BLI_path_util.h for consistency
* cleanup of #includes: removed BLI_blenlib.h in favour of direct includes of the needed headerfiles in a few places.
* removed debug print in sequencer.c
* added missing include in blenkernel/blender.c -> bad dependency, needs to be fixed still
