Add version suitable for ATH & MGC

According to Hoyt: http://accordingtohoyt.com/

Differences from ssc.js:
• Searches for the tags and classes used by the ATH & MGC WordPress themes;
• Comment box lowered to accommodate the WordPress function bar; and
• Comment hiding disabled, as it clashes with nested comments on ATH & MGC.
