This enhancement is related to [Issue #2].

Need to make an enhancement in net.sf.opensftp.impl.SftpUtil to make it work 
even when progressListener isn't set explicitly or through configuration file. 
This feature will come in next release.
It's easy. However I need to spare some time to do it.

What steps will reproduce the problem?
1. Just run the demo program and change local directories accordingly
2.
3.

What is the expected output? File uploaded to the server.
What do you see instead?

Please provide any additional information below.

Add multi-threading abilities to ProgressListener.
Currently I'm thinking to use a object pool to maintain ProgressListener 
instances.

What steps will reproduce the problem?
1. Create a file with 8bit characters on the sFTP server (ie via putty)
2. Try to get the file with opensftp after getting the filename from 'ls'

What is the expected output? What do you see instead?

Expected: Download works
Actual result: Download failes

I assume it's a problem with a different encoding and 8-bit characters in the 
filename as 'ls' shows them as questionmarks.
