Bug when logger is on and entering tide data

[o355]

Traceback (most recent call last):
  File "pyweather.py", line 6293, in <module>
    logger.debug("tide_json: %s" % astronomy_json)
NameError: name 'astronomy_json' is not defined

The code on my desktop isn't up to date, so the line number is approximate. Further investigation is needed to see if this bug affects other versions of PyWeather

If you haven't guessed already, it's due to an incorrect variable being referenced. The issue has been fixed, testing has begun.

I'm also thinking this only happens when verbosity and json verbosity are both enabled.

Issue fixed.
