Additional updates to FieldtypeComments, mainly tweaks to the previous commit rather than new features here.
Fix issue #814 where markdown in file/image descriptions was getting html stripped out incorrectly.
Update Markdown and SmartyPants versions for the Textformatters
More updates to FieldtypeComments comment system, including: 1) Comment approval links accessible from admin email notifications; 2) Support for commenter email notifications, each notification also includes an unsubscribe link; 3) Support for HTML emails; 4) Update it so that it remembers commenter email/cite in JS-based cookies rather than PHP session (which is more cache friendly). More on the way. There are a lot of updates in here so if using FieldtypeComments, I recommend testing this out only in non-production environments until we've had more testing.
