    This script does the following:
    - Adds price estimates for every quest in the game, including faerie quests
    - Adds a link to the requested item to the Shop Wizard as soon as you get the request, no need to refresh
      - Does that even for faerie quests in case you have alt accounts you want to SW in.
    - Saves the Brain Tree's answers that you got from Esophagor and fills them automatically
    - Adds a link from the Brain Tree to the Esophagor and another from the Esophagor to the Brain Tree
    
    Price estimates are retrieved from itemDB. Please consider contributing by adding a simple userscript:
