Subject: 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
