[NTFS] - Respect NTFS' file ordering when enumerating a directory. Split off part of BrowseIndexEntries() into a separate function to simplify the code.

AddNewMftEntry() - Zero the (larger) buffer for the bitmap prior to reading the bitmap.
BrowseIndexEntries() - Check sub-nodes before checking an index entry. Read and use the index bitmap when checking sub-nodes.
+BrowseSubNodeIndexEntries() - Called for sub-nodes of an index when browsing index entries.
+NtfsDumpData() - Diagnostic function which allows for visualizing a series of bytes.
