Major quality-of-life update

Added a bunch of new functionality to the game based on feedback. Full list of changes:

1. Added an option at start of game: Show/Hide images. Some players felt the artwork is so bad that it's distracting - now you can hide all images and play purely text-based. Default: Images enabled.

2. Added an option at start of game: Enable/Disable the "undo/redo" button: Some players really like to have the option to go back in time. Those players can now do that. Default: Undo/redo buttons disabled.

3. Changed the order of things requested by the man at the beginning of the game: Some players pointed out that the game goes from 0 to 100 too fast. This is an attempt to make it less 0 to 100, whilst still keeping all the content. Only the order of the things the man asks Jessica have changed.

4. Added in-game hints for player (Jessica's thoughts, etc.) in Chapter 2, to the two first scenarios - should be clear when something is not worth attempting: Some people did not like how the game gave no hints if the player was doing something right in chapter 2. Now, there's feedback for the player's actions (not all, but most) in the two first scenarios. Should feel like the player has some actual agency in the scenario.

5. Address feedback on "unrealistic scenario that company can sue Jessica for negligence" - Jessica now thinks about her situation at the company and reflects that she's consulted with three different people at the company, and they all are of the opinion that they can sue Jessica for negligence.

6. Added a "Restart game" button to all ending: Pretty much all players commented on the lack of a restart game button. A new tab or incognito mode previously served the purpose, but now there's actually a dedicated restart game button in all endings.
