General improvements in the hospital and more!

Hospital improvements: - The room indication book is now at reception. To be closer to the place where the player gets the keys;

- Side arrows indicate that the player can enter the offices, many people don't realize that there are doors in that location;

- Added an indication/tutorial, to improve the perception that you should use the keys to kill the nurses who are in the corridors of the rooms;

- There was a bug where if the player passes behind the nurses on floors 2 and 3 and came back, the nurses would not be deactivated and the player would be detected instantly; [SOLVED]

Final Hideout Improvements: - The Mantis from the last chase is a little slower; - New indications in the maze;
