- Simplify the `init` method in `models/index.js` so that it no longer
returns a promise. Easier to use.
- Eliminates the `deleteAllContent` method from `models/index.js` as it
can all be handled at the API layer in a single spot.
- Optimize `destroyAllContent` in `api/db.js`. Eliminates
double-fetching every post from the database and converting it to
JSON. Also only fetches ids from the database instead of the entire
model.
- Eliminates the custom static method `destroy` in the Post model in
favor of handling detaching tag relations in a single place (the
`destroying` event). This also eliminates a big source of unneeded
database round trips--needing to get post ids to feed into
`Post.destroy()` which then re-fetches the post again.
