calcs for comp perform. values

I didn't know if Andrew was using spreadsheet so I'm working in a copy.
I didn't add any new materials, just added data to existing ones that
will only affect OpenStuidio. I did add a few new columns. I still don't
have performance data for composite materials with no cavity insulation,
and in a few cases will need to also add a new material for these. I
think I didn't include them for walls yet.
