//
//  User interface for the scraper where the user is able to see an overview
//  of the game being scraped and an option to override the game search string.
//  Used by both single-game scraping from the GuiMetaDataEd menu as well as
//  to resolve scraping conflicts when run from GuiScraperMenu.
//  The function to properly save scraped metadata is located here too.
//
//  This GUI is called from GuiGameScraper for single-game scraping and
//  from GuiScraperMulti for multi-game scraping.
