Watch for changes in local folder and upload them to SFTP server

Just take the path to the new file and use RemotePath.TranslateLocalPathToRemote to map it to a server path, and upload the file there.

The code will be a lot simpler. All you need to do is to make sure new folders are re-created on the server.
