Addition of Error Correction Type information

Browse Source 
It would be great to start integrating ECC/EDAC support to unRAID, one of the first steps might be the relevant information from the BIOS/UEFI.

It would be good to reduce the `dmidecode -t 16` calls to one, I'm not aware if `Maximum Capacity` and `Error Correction Type` can be extracted with `awk` in one go without having to `explode` the row, otherwise it would be fine.
