This release:

• fixes issues with turtle graphics for angles that are multiples of 45 degrees.
• removes utils/zeptoforth_venv that was previously erroneously included from .tar.gz files.
• adds functionality to utils/package.sh to remove utils/zeptoforth_venv from generated .tar.gz files.

Note that the binaries have not been changed, so they will still report version 1.14.2.3.
