Added spectrum 48k buzzer sounds
Remove compilation setting for whitespace in make file
Added support for Web Audio API (chrome / safari) as well as
audio data api (firefox)
Fix instability / crashing in sound routine
Off by 1 error - small optimisation
128k Ay-3-8912 soundchip emulation routines
use model.frameLength rather than display.frameLength, and thus avoid having to pass the display object to the sound component
add correct partial decoding behaviour of AY ports as per http://www.worldofspectrum.org/faq/reference/ports.htm
fiddle the signature of ioBus.write to take the current tstate number, so that the sound module doesn't need a direct handle to the processor to call getTstates
update credits/docs
avoid error when running on a browser that supports Audio elements but not the WebAudio or AudioData APIs
