=============================================================================
Make a mergeall source-code package (a zipfile scrubbed of private content).
This is just a few moves and a zip; there are no frozen builds here.
Unlike the app/exe scripts, this may be run on Windows, Mac, or Linux.

Run this script in its own folder; it works on a copy in its folder
(which comes from an initial temp copy to avoid recursion issues).

This is now a nested step in the top-level's _publish.py, which also
generates all thumbspage galleries in the package.

*NOTE*: remove any unzipped app/exe folders in build/ before running this.

*NOTE*: moves prior zip to 'prev-' auto: back this out to save it on reruns.

[3.2] Updated for new macOS build machine, and mergeall-android-scripts
helper-scripts nesting in the source-pkg folder.  It's not clear if this 
or the Android GUI patch files should be included in Mergeall's src; these 
are maintained separately and updated often, and the scripts package adds 
an extra 30-40M.  As a compromise, the source package here includes just 
the 2 GUI patch files and the helper scripts themselves, with pointers 
to the full presentations online.  ziptools is also embedded in Mergeall 
for historical reasons (it began as a test tool here), and is now updated 
independently and often too; punt on this - too much work to rip out now...
