Signal K auto-state plugin

This plugin attempts to determine the vessel's state based on sensor values, and updates the navigation.state value accordingly.

Currently inputs used are:

• navigation.anchor.position: if an anchor is set, the vessed is set as "anchored"
• navigation.position: if the vessel moves less than 100 meters in 10 minutes, it is set as "moored", otherwise it is set as "sailing"
• propulsion.*.revolutions is used to determine whether the vessel is "sailing" or "motoring" when considered to be moving
• propulsion.*.state (value started or stopped) is used to determine whether the vessel is "sailing" or "motoring" when considered to be moving
• navigation.speedOverGround is used to trigger moored immediately if engine is stopped when speed is zero
• watch.state.onWatch is used to help eliminate "false moored" when drifting but there is an active watch schedule. Anchor alarm or stopping motor at zero speed will still trigger moored

The default means of propulsion ("sailing" or "motoring") when moving can be chosen in the plugin settings.

The vessel navigation state can be useful for AIS data, as well as for customizing boat dashboard for the current situation.
