version bump.
removed built in systems in favor of npm packages

This is a large chunk of what's required to make the system modular. Instead of everything living the the `/systems` directory, they live in the `node_modules` directory as installable packages. The system then detects them at runtime and configures them.

Currently, I have the old dnd4e pages pulled out into their own project, and they almost (but not quite) run.
Removed circular dependency.
fixed deletion.
