[DGD] Kotaka 0.9.1

[Shentino]

Did some major league cleanup of the object library, now split into
neat sections instead of lumped together into one blob of code.

I also did some exploratory coding in the Game subsystem that allows
you to plant trees and watch them grow.

Also some refinement of the ascii graphics painter to pave the way for
further layering abstractions.
