=============================================================================
Make a PyEdit source-code package (a zipfile with nested PP4E folder).
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.

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