Differentiate between Views and HTML [WIP]

*Not ready for review, I just wanted to get this online and have a place to track some thoughts publicly.*

**Changes**
- Rename `Batman.ViewStore` to `Batman.HTMLStore`
- Rename `view_store.coffee` to `html_store.coffee`
- Rename `Batman.config.viewPrefix` to `Batman.config.htmlPrefix`
- Change the default value of `Batman.config.htmlPrefix` from `views` to `html`

**Thoughts**
- It's weird that `Batman.View.store` is now a `Batman.HTMLStore`
