SFTPSync 1.6

In this release we have improved stability by eliminating crashes that could previously occur if a large number of changes occurred in a short space of time, as can typically happen when switching between version control branches, and also if changes occur after an extended period of inactivity which coulf result in the timeout of the underlying SFTP connection. We have also improved message formats in the log to make them easier to read, and also changed the behavior of the log to now show the most recent message at the TOP of the log and scroll down.
