Allow going back in time

Either just as far as the current most recent data set, or as far back as data sets can be found.

Pretty Please - This would be a big help in assessing (and improving) the accuracy of the prediction process. To be able to compare a actual flight to its prediction getting the ascent rate, descent rate and burst correct. Its even useful during a flight using the actual launch time, ascent rate etc. Even just back to the current data set would be a great help.

The new predictor (tawhiri) will support predicting back to the start of the current dataset and should be released Real Soon Now, @SteveRan. Going further back is very difficult as the datasets are huge files and we don't want to keep two on the disk, let alone mapped in memory and loaded by the predictor.
