MQTT 0.1.6

[taclane]

Plugin: https://github.com/TrunkRecorder/trunk-plugin-mqtt, release v0.1.6

New, or an update? Update, from 0.1.5 (29ec6c1) to 0.1.6 (cff4ff3). systems and the new system message carry each system's ID, WACN, NAC, RFSS and site once its control channel has stated them, and systems is sent again (retained) when they change, as Trunk Recorder's MQTT plugin did. Needs Trunk Recorder Pro v0.1.12 or newer for the values; older versions will continue to report zeroes. The plugin SDK is built from the Trunk Recorder Pro v0.1.12 tag. ./check plugins/mqtt.json passes for all four platforms.

For the reviewer

• The source is public, and its license allows it to be listed
• It does what it says, and sends nothing anywhere the user didn't configure
• Secrets are marked x-secret, and never logged
• It copes without M4A, if it asks for it
• It starts with its default settings, or says what to set
• The id is fitting and doesn't impersonate anyone
• For an update: read the compare from the old entry's commit to the new one
