Added read-only attachments to the Releases API (#63)

* Added assets (attachments) to the releases.

- Added three new endpoints to the release api for attachments.
 - List assets: GET /repos/:owner/:repo/releases/:id/assets
 - Get single asset: GET /repos/:owner/:repo/releases/assets/:id
 - Get /repos/:owner/:repo/releases/latest` that gets  the latest published full release for the repository. Draft releases and prereleases are not returned by this endpoint.
