HTTP step: show progress

[Rogier]

When downloading a large file through with the HTTP step, you just see a growing line of dots, like:

C:\Local\file.zip <- /RemoteDir/file.zip
.................................................. .......

And no way to guess how much is done

Would be very nice if you can simply add a percentage, or (because total filesize is something unknown, and then neither is percentage) the amount of downloaded data.

The FTP step does this nicely, it prints percentages like this:
...2%...4%...6%..etc
