[Fluxus] (ga)

hi,

i added a new function, (ga) to get the contents the audio buffer. this 
makes it possible to display a scope. committed to git.

hackpact #28 demo: http://www.vimeo.com/6791035

there's one thing with it. although my buffer size is 2048, and i 
receive a vector of 2048 elements, only the first 128 elements are 
usable, the rest is zero. is this a jack thing? or am i missing something?

best,
gabor
