Realized we have a conflict in settings names between S3 hosted
static content and S3 hosted uploaded media content. Prefixing
static content with `STATIC_CONTENT_`
- We don't need to be setting DEFAULT_FILE_STORAGE after static changes
- Need to be able to correctly pass binary files (images, etc) so need
to avoid converting to UTF-8 after retrieving from S3
- Moved to simpler CBV
Includes these failing tests:
```
=============================== short test summary info ================================

```
* Stubbed out TemplateView for rendering markdown files
* Added a BoostRenderer class to parse the markdown files to support the first iteration of a youtube shortcode and also a Pygments renderer for code blocks.
* Added default styles for some common markup so the rendered markdown looks better.
The pygments renderer is set to use Solarized Dark right now because that’s the closest I see that matches the design of the site. This can be changed in the class.
