Hello, stalkers!

I saw a few videos on YouTube with my game and I figured out, that players need some kind of tutorial.
Warning, this update can't load saves from 1.0 game, so if you want install this game version, you'll ned to start new game.

Features:
+ Added a help button in the skills window with skills descriptions.
+ Added tutorials at the first levels of the game.

Fixes:
- Changed a little door trigger position at the "Find Red's friend Whistler in the sewer" level.
- Some cosmetics change at the same level.

How to go forward in the radioactive tunnel by Red's quest:
