The last few steps of livecd-iso-to-disk.sh usually take a long time
While waiting, one sees the message "Copying live image to USB stick"
without any indication of progress. It would be great if a progress
bar is displayed.
The attached patch implements a progress bar with ETA information. (I
was inspired by http://www.theiling.de/projects/bar.html for this
patch.) Hope everyone finds this useful.

Swee Heng
