Add "always open" mode.

Scenario 2

1. The test rig is powered on and the daemon and VSCP Works are started.
   

2. Events (temperature measurements) are received in the VSCP Client window.
   

3. The power from the Frankfurt module is powered off and 2 seconds later on.
   

4. No temperature events are received. // I waited > 10 minutes
   

5. VSCP Works is closed and the Daemon is restarted.
   

6. The Daemon reports a driver failure for the Frankfurt module (see attached pic).
   

7. The Frankfurt module is powered off and the daemon is closed.
   

8. The Frankfurt module is powered on and the daemon is started. The driver is successfully loaded.
   

9. VSCP Works is started and the temperature events are received in the client window.
   

10. The scenario does NOT always happen when I cycle the power on the Frankfurt module.

This will close the channel (it is opened when the driver is opened). A common problem with all CAN adapters also. It makes me think if if it wouldn't be a good thing to have a configurable always open mode for it. I will make a note for that.
