New intro added to part one to clear some questions regarding the side-story

Hello! 

I added a new intro for the side-story to clear some questions regarding why you start in the halloween side-story and not the "main game".

Some people were getting confused so I decided to explain it at the start of the game.

Also testing new stuff you can check patreon for more info (it's free).

Changelog:

-New intro added to the game to explain the status of the game and halloween side-story.
