[IriDium]

Now fully upgraded. No issues with CEC - TV and AVR switch on/off as expected.

To get to this state I had to:

1) Change xbian.list as described above.
2) Upgraded via command line - xbian-config didn't seem to work. (About 60 packages)
3) After reboot used ssh xbian-config to update mirrors, the update and upgrade. (About 12 packages) - this sets stable, staging and devel as active.
4) After reboot used ssh xbian-config to update and upgrade. (About 5 packages).

All worked as expected.
