Minor changes made. Also packaged all the files together, because there's a lot more downloads for the client alone than for the `vol1.pck` XD

Changelog:

• added a message when the song is changing
• disabled pausing (and thus rewinding) when the song is changing
• web browser export
• blacklisted some commands for the browser export
• scene generating will overwrite the old ones (made in case I decide to update already released volumes)
