Changes since version 5.2

Minor changes and bug fixes

Fixed a bug where the data connection sometimes froze until a FileSystemIOException was eventually thrown.
SFTP: Fixed a bug where the date/time of files of SFtpFile and SFtpFolder items were always set to the January 1st 1970.
Common exceptions thrown after the FileSystemEvents.ItemException event now preserve the original stack trace to aid debugging. If the exception was changed in the event handler, it is thrown as-is.
