Stations named after your boat, and signed token requests: Signal K AIS plugin 0.6.0

Your station on aiscast takes your boat's name, the vessel name set in Signal K, while Share my own ship is on. Turning that switch off removes the name, so the station never says where the boat is. There is nothing to set up.
The plugin signs its token requests with the boat's key, so nobody else can get a token for your station. After the upgrade it requests a new token once.
Plugin Config shows the address of this boat's station page on openwaters.io under Advanced → Access token, to copy into a browser, so you can see what your receiver is contributing.
A pasted token that aiscast refuses now says how to fix it: clear Advanced → Access token and the plugin goes back to its own token. Tokens from openwaters.io/ais/token that are bound to a network address stop working when that address changes, as it does on Starlink and cellular. The plugin's own token works from any address.
