Whoopsies

I'm still working on this. I've got two updates semi-finished and need to poke my pre-reader a bit more.

I also updated the tags a bit (for some reason I thought the Crossover tag superseded the Human one) and re-evaluated the rating. It's now Teen, same as all good Ar Tonelico games. A small story plan change is reflected in the characters bar.

Also I realized I never described what Mir's cutie mark looks like, so that was added to chapter 1. It'll be described again when it's relevent.
