patch 2.7 - Floorboard rework and notation.

CHANGES

+ changed how the boards work

- they now multiply prior bought buildings.

+added notation to simplify starfall and starfall per second up to the trillions.

- If you get past the notation currently in the game, comment a screen shot and I'll add it.

So I've been worried about balancing for a while now, but honestly after looking at it, the balancing is pretty good so far. So I'm mostly going to focus on balancing later down the line, towards the first main launch.
