Renamed to octopress-plugins, added local Sass plugin
Vastly improved plugin layouts, added template tags

- Layouts now directly register with Jekyll. This cleaned up a lot of
  code, and fixed bugs with rendering markdown files properly.
- Added content_for, yield, wrap_yield, head, footer, and script tags. This will
  make it easier for users to inject content into themes without
  having to customize them directly.
