v.1.3.0 - Really Big Update

- Add donor.

- Thanks to the help of 融雪_杜鹃花 on Bilibili, the first chapter and all necessary menu elements have been translated into simplified Chinese! The music and behind the scenes pages are still not translated for now as they are less important.

- Changed the "Not Guilty" text to white on black instead of black on white as it should be.

- Fixed some script errors.

- To accomodate the new language, the save and load system was modified again. Fortunately, this will (should) not affect older saves from 1.2.5.

- Modified the setup of the credits page so that each person who helped directly has links to their respective pages that are clickable.
