JDK FTP support

[David Hansmann]

Hi,

thanks for you response! I guess I'll wait for further developement then...

Once your API is merged I might code some unit tests that test the same 
functionality on both your API and the JFtp one for example, so feel
free to tell me what exactly you need then ;)

Greetings,

David
