Hey Phil,
We have a problem with Python 3.6 (and apparently 3.5 as well, although
I'm not seeing it right now):
$ python3.6 openlp.py
Traceback (most recent call last):
File "openlp.py", line 44, in <module>
main()
File "openlp/core/__init__.py", line 440, in main
settings.upgrade_settings()
File "openlp/core/common/settings.py", line 495, in upgrade_settings
self.setValue(new_key, old_value)
File "openlp/core/common/settings.py", line 525, in setValue
value = json.dumps(value, cls=OpenLPJsonEncoder)
File "/usr/lib/python3.6/json/__init__.py", line 238, in dumps
**kw).encode(obj)
File "openlp/core/common/json.py", line 74, in __init__
super().__init__(skipkeys, ensure_ascii, check_circular, allow_nan,
sort_keys, indent, separators, default)
TypeError: __init__() takes 1 positional argument but 9 were given
They've removed the __init__() method from the C implementation of the
json module. Everything is now set up in __new__.

It looks like you're not supposed to subclass JSONEncoder anymore,
you're supposed to pass it a default instead:

Ugh, that's a pain.
