SWORD: (SPANISH DEMO) Needs to be ID'd as a demo in order to be fully playable

[IlDucci]

Broken Sword 1's Spanish demo was mistaken as the full game by the emulator, and thus, some weird behavior appears:

• Every time a saved game is loaded, the game asks for CD1. Hitting a key removes this message.
• It's possible to reach the map (by going after the guy with the pick) and crash the game attempting to go to the Police Station.
• Instead of displaying the enddemo video after exiting the sewers, George is able to exit the sewer into the next screen from the final game. The subtitles are correct, but the voices are not available (obviously).
• The website's custom subtitles for enddemo SHOULD NOT BE PLAYED in this release, as the video is quite different (Just the game's logo, with a typo, and Revolution and Virgin logos).
