0.7.7 public release + about 0.7.8

Hi! Hope everyone is doing well!

I forgot to set a deadline for the poll as usual lol. Still, it's clear which option won, so from now on the changelog will be available to everyone.

For 0.7.8, I've decided on Alexis and Kate. I'm not sure yet if there'll be anyone else since Kate's got four scenes, but we'll see! For this week, I've finally started writing a character interaction (between Abigail and Sarah) section again. For the last few updates, I just haven't been able to come up with one that doesn't feel forced. But now, with Grace's introduction, it came naturally.

Thank you for your support! :)
