New corporate earnings #106

This PR revises the process of forecasting corporate earnings before tax, to instead forecast each of its components. This will be useful for modeling each component in the future.

The new version underestimates tax revenue, whereas the previous version overestimated it. This is largely due to the treatment of interest deductibility (which is modeled for the nonfinancial corporate sector), and it will be resolved when the Corporation class is split into different corporations for each industrial sector.
