C# FastFileInfo

This is an updated version of the 'A-Faster-Directory-Enumerator' on codeproject.

MoveNext() is rewritten without recursion. (C:\Windows\winsxs\ was causing a stack overflow exception due to too many folders and repeated calls to MoveNext, causing the entire application to abruptly crash).

Increased speed 60% by not using Directory.GetDirectories(...), and if the search filter is * or *.* then the code is even faster because a separate call to fetch the directories is not required.

Increased speed another 25% by using FindFirstFileEx with the basic option (saves time by not requesting the cAlternateName).
