T3D 1.1 Preview - PlatformWin32 Semaphore code - LOGGED (THREED-1582)

The path to the /platformWin32 semaphore code is inconsistent with mutex.cpp and thread.cpp which are both located in platformWin32/threads directory. However the semaphore code is located in the /platformWin32 root directory under the name winSemaphore.cpp.

Not really a high priority bug but an inconsistency with mutex and thread code.
