Enhance the download rate output to include downloaded file name

While doing a build today, i noticed something that is a little confusing.

Take the following output

Downloading: http://localhost:8012/somesuperbig.jar
Downloading: http://localhost:8012/somesmall.jar
5 KB downloaded at 10.4 KB/sec
Downloading: http://localhost:8012/someotherbig.jar
500 MB downloaded at 19.2 KB/sec
500 MB downloaded at 19.2 KB/sec

While this is occurring, you have no idea which file downloaded at a size of 5KB (only once its done can you figure it out, and this is simple example for purpose of ticket).

Would be nice to see something like this

500 MB downloaded at 19.2 KB/sec (http://localhost:8012/someotherbig.jar)

for example
