Fairlight Pro update

Fairlight Pro updates for iOS5 and a few more bits:

iOS 5 Compatibility Release

• fixes crash on launch in iPad in iOS 5
• fixes missing sound on voice preview PLAY button in iOS 5

Other updates

• Changes voice attack and release to be time instead of number of samples, so attack and decay are now the same for all pitches.
• Page R loop mode button now works correctly after selecting a pattern.
• Ringer / mute switch now ignored in all modes.
• Newsletter subscription preferences are now stored in iCloud, so you shouldn't be asked again when re-installing.
