Move PluginAdapter to core (#615)

There's no reason for it to be in `app` - the concepts it contains are
core concepts, e.g. node types and graphs.

For now I'm leaving the `NodeType` and `EdgeType` interfaces with the
PluginAdapter. They may move later, but I'm relucant to clutter the
graph class more, and all I need for now is that they live in core.

Test plan: It's just a move/rename, so `yarn test` is amply sufficient.
