1. Added new include_code tag to allow auhtors to insert files from the file system with syntax highligting and a download link

2. Improved the gist tag to properly insert the sources in <noscript> tags
3. Improved semantics in the blockquote plugin and DRYed things up.
4. Pygments caching now stores to the _code_cache directory by default
5. Added a configuration for the default include_code directory
6. Updated the .gitignore
