Various updates all around

There were several small updates on various pages.

I noticed the new Sonos firmware required some changes to the script, so this is documented as well. I even provided a nice patch so you don't have to make the changes manually.

Via decided to list the connector type in their newest manual, so now it is possible to buy the correct connectors to make the hardware hacking easier.
They also released an updated BIOS.

I also am using my DC powersupply/UPS and it is working great! :-)
The downside is there is still no monitoring done, but that will be "fixed" in the future.
