Latest update additions and fixes

Update launched today for Leas: City of the Sun. Here's what's new :)

• Added checkpoints to the beginning of all chapters (except chapter one, since that's just the same as restarting the game).

• Fixed an issue where the chapter nine checkpoint wasn't working once you got to chapter ten.

• Fixed an issue where in chapter 13 one character was incorrectly said to be alive (making this one vague to avoid spoilers).

• Fixed an issue where if romancing Keo but traveling with Rin in chapter 9, Keo incorrectly acts as though you're traveling with Wren instead.

• Corrected some typos.

• Added some behind-the-scenes variables to track things for future games.
