Subject: Refactored inclusion of disqus script

- Added ARIA setting `aria-live="polite"` to comment output
- Removed duplicate <div id="disqus_thread"> from page/post templates
- Moved blocking JavaScript loading to the end of the document body.
- Merged JavaScript code for index and pages/posts using conditionals
- Moved global JavaScript disqus variables into the anonymous function to stop pollution of global namespace
