Updated demo!

This updated version of the demo is meant to speed things up a notch and give more incentive for the player to explore:

- Cordelia can now be rescued a bit earlier, which means the Temple of Trials is also accessible sooner for the player to learn new skills.

- The cost of learning "Dash" at the ToT has also been reduced from 300 to 200 TYPs.

- Brook the librarian is now present in the demo and can be rescued early on. This is meant to encourage the player to find the missing pages while exploring
and gathering on the maps, and doing so is also rewarding for learning gameplay tips, reading some lore, as well as discovering a few secrets.

- Zu Mu the ninja is now also available in the demo (though not right from the start): rescuing him will unlock fast travel, which will make moving around from place
to place easier without having to walk everywhere.

- The cost of materials for crafting some tools has also been reduced.

All in all, these changes should alleviate the feeling of monotony that could be felt when exploring the different maps over time, although all this is left up to the player: you can still take as much time as you need!

Quality of life changes:

- Picking up an item will now display the amount you currently have in your inventory. This will avoid unnecessary trips to the items menu when collecting and gathering.

- Opening and exiting the menus and cancelling are now assigned to their own respective keys/buttons.

- Extra tutorial messages have been implemented to explain some gameplay aspects under certain conditions.
