Change column titles and order

[tsmbland]

Description

In line with the discussion here, I'm changing some of the column titles to be clearer. I've also made the column order more consistent between tables.

There are a few columns which I think should be just id. I'd request changes but I'm going away and don't want to block merging.

I think I may have missed something, but what are agent pairs about?

[tsmbland]

This is because agents have typically been made up of new and retrofit shares, so this is a way to link them together. I might change this later.
