Bug fix (v1.1)

Just fixed a section in the Spilt Milk scenario which broke some of the links. As simple as it is to build a hypertext game, sometimes little syntactic errors happen.

This update also has some typos fixed, but leaves the essay as is (for now). Being written in Twine exclusively, and not in a word processor first, there are undoubtedly more typos I've missed due to no red squiggly lines helping me.
