Added Gallery

Hey everyone!

I got some feedback that the game could use a gallery feature, so I just finished adding that to the game. As well, I've had some feedback about Samantha's Villain mode trial being too difficult, some people are for some reason losing even when following the walkthrough exactly. So, I tweaked it to be a little more lenient. 

Due to a bug I discovered while working on this update, you will need to re-view Miranda Mode's ending to unlock Miranda Mode CGs int he gallery, but the main story and villain mode CGs should work right away if you've already cleared them.

Thanks everyone for your support. :)
