Fix Publishing Dates

I don't know offhand when Jane Austen published Sense and Sensibility, but I strongly suspect it was not 2003. Leo Tolstoy, having died in 1910, did not release much in the 2010s.

A lot of these dates are wildly incorrect. I suspect this may have been done automatically, perhaps grabbing whatever date GoodReads has, but clearly the information gleaned was incorrect and needs to be reviewed more thoroughly.
