New TimePoint added: first humans (195 kya)

Following some feedback, we have added a new TimePoint to the default Organic Evolution TimeLine. Modern humans arose somewhere in the region of 100,000 to 300,000 years ago. (Marking age uncertainty is on the development wishlist!)

As previously indicated, we are currently basing much of the default TimeLine on the New Scientist Evolution and Becoming Human timelines, which place this particular event at 195,000 years ago. It seemed like a gap in the current TimeLine and a useful TimePoint to have.

More information regarding our default TimeLine will follow shortly.
