DreamShell v4.0.0 Release

[pcwzrd13]

Been doing more CDDA testing and I gotta say @SWAT, the improvements are astounding! Distortion is completely gone in some games like MagForce Racing, Speed Devils, and Star Wars: Demolition (which doesn't freeze with DMA anymore either). The music sounds just like it's playing from the GD! Well done @SWAT! Well done!

There are still issues with some games but it's so much better! Been updating my spreadsheet with details (anything marked with "DS 4.0" has been tested with this release).
