Added sound tracker used to compose Face Hugger's Ultimate Megademo songs !

As mentioned during the Face Hugger's interview, the author used a custom sound tracker to compose the musics of its Ultimate Megademo. The disc image of this tracker, mostly written using BASIC programming language (even the sound player !), has been added to the article. Feel free to discover it : the user interface is quite horrible but the demo song itself is actually very good ! Of course, this is released for historical purposes only and absolutely not intended for serious usage - nor Face Hugger or this site will provide any kind of support about it. Download link is located at the end of the interview (as a bonus material). Thank you Andreas, you rock! :)
