zufortune.py

"""
zufortune.py is a short script that dumps the maximum possible Zulip messages, as allowed by the Zulip API, into a local file in the format expected for files as inputs to the Unix fortune command.
It also ensures that there are no message duplicates in the file from previous runs. It then updates the generated fortune binary file.
