[DGD] Kotaka version 0.19

[Raymond Jennings]

* Headers have been revamped

Mostly just a cleanup

* Algorithms

For greater maintenance ease, all algorithm type stuff, such as random
number genration, sorting, etc has been confined to its own subsystem.

* Timer removal

I plan to rewrite in game timing

* i3 management

There are now commands which can be used to manage i3 channels

* Subsystem management

There are now commands to boot, reboot, and shutdown a subsystem.

Shutting down a subsystem deletes all objects it owns and removes it from
the subsystem list.

Needs work, especially with dependencies, but it's a start.

* Nil handling removed

I decided that the savings in data wasn't worth the added code complexity,
so now arrays and mappings used for in game object lists (archetypes,
inventory etc) are now assumed to be non nil.

A quick "touchall ~Game/obj/thing" after recompiling should clean things up.
