Improved progress information when reports are loading

It's difficult to determine how long a report is going to take to load. This can be for a number of reasons, including the fact that Spotfire will likely not know how much data is going to be returned from databases. So it's accepted that a "% Complete" type metric is always going to be difficult. However, it seems like the information currently being received is less useful than information received in the past. Users used to be able to see how many rows of data were being returned from a database query - now we see the amount of SBDF data, which makes much less sense to users.

So ideally we would show a % Complete bar, but if this is simply too speculative, then at least show the number of rows being returned from a database rather than the amount of SBDF data being loaded.
