SSL/TLS support for InfluxDB and MQTT scripts Copy the command line option handling into the status scripts to facilitate this. Also copy the setting from env from dishStatusInflux_cron.py. Better error handling for failures while writing to the data backend. Error printing verbosity is now a bit inconsistent, but I'll address that separately. Still to be done is dishStatusInflux_cron.py, pending a decision on what to do with that script, given that dishStatusInflux.py can now be run in one-shot mode. This is related to issue #2.
