Version 2 is ready!

Market calculations added

When you mouse over the yellow columns, for any product, that amount is multiplied by the market value and displayed to you in the input field on the right. (i have stretched the field to fit billion dollar figures)

This applies to:
-Buy goods
-Buy Tech

Other changes:
Formatting of surrounding table cells to make sure it all fits neatly.
