Gallery feature, and early Chat History feature

One Possible Future has gained two features:

1. A gallery of unlockable images, accessible from the title menu. Images are unlocked as they're discovered in the game.
2. A first pass at a chat history feature. It's currently accessible only via the hamburger menu when exploring, NOT during conversations, which is obviously less than ideal! Larger UI changes will be needed to improve this.

These improvements will almost certainly be making their way into For One Year, as well :)

Thanks for playing, and have fun ;)
