MacOS pspp 1.2.0 application bundle release

[Friedrich Beckmann]

Dear friends,

i have produced a MacOS pspp 1.2.0 application bundle.

See: https://www.hs-augsburg.de/homes/beckmanf/pspp/

The bundle is created on MacOS 10.13.6 (High Sierra). Please
send a feedback when you test the bundle on other MacOS Versions.

Johns spread-sheet-widget is really fast! You may try the grid.sps
from the examples and modify it to produce 50000 cases with 1000 variables
and see how fast you can still scroll!

Fritz
