tpfand doesn't work without HAL
As Ubuntu 10.04 does not depend on HAL anymore and I'm pretty sure it is removed from installation packages, tpfand has to be able to work without it. It doesn't now, python says it can't concatenate string with None.
I've tried to make it call to DeviceKit to get vendor and such information from there instead, but seems like DeviceKit just don't have any devices similar to 'computer' one.
So, I just replaced None with empty strings and that works. It won't show the proper laptop model but that is better than crashing. Patch is attached.
BTW would be good if package said it did depend on HAL.
