win32pthreads: Changed from _beginthreadex to CreateThread, which is the preferred method of creating threads when using dynamic CRT linking.

PCSX2/Win32:
 * Assigned names to the threads so that they show up nicely in the debugger.
 * Added more error checking in the new stdout/stderr PipeRedirection code, hopefully fixing Issue 422 (but can't reproduce the error here to be sure).
