v3.0beta update - more options

Nearly done now with the total re-do of the sound system. Much happier with the new setup and best of all, it let's me add this feature: You can now control the volume of the music and sound in the Options menu.

Still missing a few sound effects, but they'll be back in a day or too. Closing in on the final 3.0 version. Now is the time to send any feedback or suggestions!
