Extracting Value Chain values

[villyc]

I'm back working with the value chain, and found myself extracting values for revenue, cost, production, jobs male, jobs female, for each group in the model. Pretty tedious, and I realized that there were problems with some of the values so I'll have to do this more than once. Thus, would be nice to add a results spreadsheets, where the categories revenue, … are column headings and the groups (processors, distributors, etc) are rows.

VC: Guess we might as well take all of the rows from our present results table in the value chain (production, production live weight, ….) and make them all columns in the big results table

VC: Actually, it's fine just to add a "save" button and save it all to a csv file

Value Chain now connected to the auto-save structure in EwE (#1210)
Added a save button to the results form

Note: this does not work yet for the equilibrium search option.
