Modifications to pull out the sensor monitoring and Tinamous notification into a Monitor class that can publish sensor readings at it's own pace and allow much faster UI updates from the sensor readings.

Other general changes to tidy up the display, improve messages, disable rfid, button, and status message reading.

Updated models from Tinamous to use string for id's as these have changed from longs to Guids.

Added light level logging.

Added channel identifier to Tinamous measurement logging, even though it defaults to 0 anyway.

Added M2Mqtt to start experimenting with that for MQTT feed of sensor data as well.
