[Jprogramming] 807 beta-e zip install packages for windows/linux/macos

Eric,
  That's indeed correct. The output from j807 on the mac mini is wrong, 
even though it dosen't crash:
    JVERSION
Engine: j806/j64nonavx/darwin
Release: commercial/2017-11-06T10:18:00
Library: 8.06.09
Qt IDE: 1.6.2s/5.6.3
Platform: Darwin 64
.... here's what it should do
── (5 of 15) Examples 
───────────────────────────────────────
Here is a simple example:
)
    fftw i.8
28 _4j9.65685 _4j4 _4j1.65685 _4 _4j_1.65685 _4j_4 _4j_9.65685
... and
require 'numeric'
    clean (dfft - fftw) i.8
0 0 0 0 0 0 0 0

But under j807:
    JVERSION
Engine: j807/j64nonavx/darwin
Beta-e: commercial/2018-05-25T12:55:54
Library: 8.07.15
Qt IDE: 1.7.1/5.9.5
Platform: Darwin 64
.... we get
── (5 of 15) Examples 
───────────────────────────────────────
Here is a simple example:
)
    fftw i.8
0 0 0 0 0 0 0 0
and ...
require 'numeric'
    clean (dfft - fftw) i.8
28 _4j9.65685 _4j4 _4j1.65685 _4 _4j_1.65685 _4j_4 _4j_9.65685

The results further along under j807 are just garbage, e.g.,

── (10 of 15) Examples (ctd)

)
    A=: j./ ?. 1 + i. 2 3 4 5 6 7 8

    $A
3 4 5 6 7 8

    $B=: fftw A
3 4 5 6 7 8

    $C=: ifftw B
3 4 5 6 7 8

    +/ , clean A - C      NB. A matches C
