Tor Detection failures resolved

We have now tracked down and resolved the issue of Tor Detection not working in some instances. Tor Detection should now be working all the time. The issue was isolated to lookups on our HTML interface, and was failing when multiple lookups to the same IP Address or Domain name were done. The first lookup worked fine - subsequent lookups could not be counted on to be accurate.

Our XML lookup interface was not subject to this issue.

We also identified and fixed a few minor issues along the way, and were pleasantly surprised to find a way to speed up the Real-Time Tor Detection algorithm by 5 times - what previously required 4-5 seconds on average now takes about 1 second to accomplish the same thing.
