Bad ait-plot-config JSON object crashes the GUI

[jordanpadams]

I was missing a quote in one of my plot configs, and it started throwing continuous errors. We should probably catch a bad JSON object and just move on.

Config

                <ait-plot-config>
                  {
                    "foobar": "CCE AC Voltage,
                    "ylabel": "Voltage (DN)"
                  }
                </ait-plot-config>

Error

+1, good call @jordanpadams. That's not terribly user-friendly as is.
