GMS SAGARMATHA added to the PC pack!

To celebrate the release of Wallflower Part 1, I decided to round out new players' LL0 selections to include the GMS Sagarmatha, an older, more heavily armored model compared to the smaller and higher spec Everest. I haven't decided if I'm going to do the Worldkiller Genghis and the Ranger Swallowtail next, or if I'm going to do more NPCs next. We'll see how the mood strikes me!
