Readibility on download progress bar text

[YChao]

The caption text in the download progress bar is of the same color as the bar. When the progress is more than around 60%, the percentage caption text will be invisible under the progress bar. Ideally there should be some XOR or different color/gray scale to avoid this. (seen with OS542 on a B4 machine)

Patch to display percent in a seperate line

So the display of the download info will probably go away from the clipboard. I added the patch to fix the issue above for reference if we decide otherwise or if we want this in trial-3.
