Function ddio_CleanPath

ddio/winfile.cpp:383–488

given a path, it cleans it up (if the path is c:\windows\..\dos it would make it c:\dos) srcPath is the original path dest is the finished cleaned path. dest should be at least _MAX_PATH in size

//	dest is the finished cleaned path.
//		dest should be at least _MAX_PATH in size
