Minor experimental changes to the download progress bar:

Browse Source 
* change to Mb and Gb for both total size and transfer rate if needed
* round up to 1 second for downloads that were between 1s and 0.5s

This function needs some serious looking at, as it's probably not 64bit safe (thus the "wrong calculation" problem on the list).
