Subject: [PATCH] Replace regex extraction with brace-counting for __OO_STATE__

The regex .*? (non-greedy) fails on 500K+ JSON due to Java regex
backtracking limits, causing truncated data (only 3 of 6 menus
extracted). Replace all 3 extraction points with cfscript
brace-counting that reliably handles any JSON size.

Also decode HTML entities (&amp; -> &, &lt; -> <, etc.) from
Chrome View Source saves.
