Add an book to the tutorial for custom your Party, like the Storm of Zehir

Instructions : Copy all the archive content to your game folder
Overwrite if needed

Changelogs :
1.1 : fix a issue that caused the mod not to work (by bad i have forget a file xD)
and i have added the same book in the Sunken Flagon (in french : La Chope sans fond)
1.0 : main version (not work)

Infos : the modules are saved in the savegames, so if you play without the mod, you can't add the mod after
So you need start an new campaign for use the mod.

I need reports
Please send me if you find bugs
