* Adding zeroed speed initialisation to modes that do not support speed to avoid bad save values in profile
* Bad values in saved profile will corrupt brightness calculation on load.
* Aligning profile version and header string
* Adding profile validation logging
* Adding success / failure logging for each controller when attempting to load profile
