Add inline adapter.

Example

```js
conductor.load(cardUrl, cardId, {
  adapter: Conductor.adapters.inline
});
```

Also upgrade Oasis, which adds support for adapter-unsupported capabilities and
toleration of duplicate capabilities.
Add a dev build of conductor.

Use that dev build in tests.

The dev build adds debug on error in RSVP.
Add some `History.md`.
