ipoke~, butt~ and += now in version 2

    Dear all
    My very modest contribution to the Max/MSP community is now in v.2
    for Mac (UB)
    ipoke~ in an interpolating buffer writer, filling the gab between non-
    consecutive addresses. This is needed for emulating a variable
    sampling rate digital delay for instance. for version 2, I've
    optimised the filling algorithm and fixed a bug that caused Max to
    crash. The code is about twice as fast.
    butt~ is a dirty filter. A simple trick tickling the feedback buffer
    of a biquad. The v.2 is now Altivec coded, so the code is about 4
    times as fast. Even the scalar mode is way faster due to some
    profiling, about twice as fast. The source is available on the dev
    forum...
    finally, plusequals (+=) is a simple yet effecient accum. Not really
    needed but sweet ;-)
    All bug reports are welcome as usual. I can send the new code to
    anyone who wants to compile it for XP.

      Important announcement to anyone who downloaded butt~ (sorry for the noise for the vast majority who didn't ;-)
      There was a little Altivec bug that could blow your speakers out!!!
