Subject: [PATCH] Add swigRaw option

Writer may not want their HTML to be processed by the swig templating
system that hexo applies to HTML by default. Offer an option to disable
swig from template via the {% raw %} tag.

 - **autolink** - Enable autolink for URLs. E.g. `http://hexo.io` will become `<a href="http://hexo.io">http://hexo.io</a>`.
+- **swigRaw** - Escape the output in a swig `{% raw %}` tag. This will keep your template from being parse by the default hexo swig renderer.
