Release 0.0.2

## 0.0.2 — November 3, 2013

-   [ZH-22]: Persist metadata using [Redis].
-   Implement basic `Content` model.
-   Extract `Fetcher` and `Processor` from inline code.
-   Link to metadata from view page.
-   Add support for [VIPS] to improve speed of generating DZIs:
    -   Upgrade [deepzoomtools] to version 0.0.4.
    -   Setup [Ansible] [VIPS] role.
-   Improve [Ansible] setup and deployment:
    -   Separate boostrap from setup phase. Bootstrap requires `root` access
        to create admin user so setup can simply use admin user.
    -   Run app on port 3000 and map it to port 80. Allows us to run the app
        with an unprivileged admin user instead of `root`.
