GOB: Version from main menu shows nothing for GOG version

[antoniou79]

This is tested with Goblins 3, GOG version, ScummVM 2.8.0 and 2.9.0git current master HEAD.

When selecting Version from the in-game menu (top of the screen, select the "diskette" icon and then "VERSION"), the game shows seemingly badly initialized text that makes little sense.

This is because the GOG version is missing the "VERSION" file, which is, as far as I can tell, what has to be read to correctly display the VERSION info for the game.

Since the game is detected as "Goblins Quest 3 (CD v1.02/DOS/English)" by ScummVM detection, it could be possible to implement a fallback for this case and display a version text based on the detection findings.

I am attaching screenshot of how it looks without VERSION (GOG version), and how it should look properly.
