Send radar state when enabling radar.

This should set the proper auto range (and other state) in scenarios such as:

- Radar on, on Auto range
- Switch radar off
- Zoom in or out
- Switch radar on

where the 'switch radar off' can even entail a physical switch off.
Introduce VerboseLog=2 for really verbose logging
... so that VerboseLog=1 only shows a little less information.
