Trevor Thompson 0409b3161e [NTFS] Add support for creating new MFT entries:
+AddStandardInformation(), +AddData(), +AddFileName() - Add attributes to a file record
+NtfsCreateFileRecord() - Creates a new file record and saves it to the MFT.
+AddNewMftEntry() - Adds a file record to the MFT.
NtfsCreateFile() - Modified to create a file record on a file-creation request (file creation is still unsupported; the created file needs to be added to the parent's directory index).
+SetFileRecordEnd() - Establishes a new file record size
UpdateFileRecord() - Improved documentation
InternalSetResidentAttributeLength() - Updated to use SetFileRecordEnd().

When writing to a file, increase the file size if trying to write past the end.
*FindAttribute() has been given an optional pointer to a ULONG that will receive the offset of the found attribute from the beginning of the record. This is to allow for found attributes to be written back into their file records.
+SetAttributeDataLength()
+UpdateFileRecord() - Updates a file record in the master file table at a given index.
+AddFixupArray() - Prepares a file record or directory index for writing to the disk.
