Edit to Sideswipe

I mentioned this in an author's note on the sideswipe, but a good number of people have already read it so I wanted to make this to inform those of you that have. I originally posted the wrong edit of the sideswipe, and have since fixed it. To sum up the changes for you (so you don't have to reread it) I cut down on some unnecessary dialogue, fixed a continuity error where Derpy was made a third year instead of a second year, and identified the Dazzlings properly as Hippocampi (instead of a variety of pony races). Again, I wanted you all to be informed, so there would not be any confusion in later chapters. Thank you.
