Add auto_tagk and auto_tagv fields to the Config class along with defaults
(to true for both) in preparation for #331.
Create Config.loadStaticVariables() to load the static variables whenever a
config value changes. Now overrideConfig() will reload the statics.
Change setAutoMetric() so that it will update the hash map with the given value
in case users access the config from the GUI and have toggled the flag via CLI.
