Python File Saver HTTP Server for TiddlyWiki 5

pytid

#!/usr/bin/env python3
"""
TiddlyWiki 5 saver in the form of a Python 3 http.server.

Start script in directory with TiddlyWiki's, go to http://localhost:8181,
select the TiddlyWiki you want, and this server should handle saving via
TiddlyWiki 5 PUT save method.

Based on: https://gist.github.com/jimfoltz/ee791c1bdd30ce137bc23cce826096da
  - why not just use the Ruby one? some environments don't have Ruby, some
    people feel more comfortable with Python.
