Completed content just before the first ending

I'm getting close to translating content up to the first ending now. There's some minor branching I have to bugtest once work on the first ending beings in earnest, so I released content up to the soft start of the first ending.

The first ending will open up a couple things, including the remainder of the "Shallow Memories" and the first sneak peek of the "Enlightenment Realm". Two image-based options will appear there, which I plan to translate by the time of the next release. It also allows switching faction without having to mess with saves.

I also went ahead and translated a remaining untranslated image in the story battle screen for the White Side.
