folding.js not available on report pages

[kenclary@…]

• folding.js is not included on report pages
• jQuery(".foldable").enableFolding(true, true) is not called on report pages

Via plugins (I'm using ​http://trac-hacks.org/wiki/CollapsiblePlugin, but I've found others that simply add "foldable" divs), it is possible to create collapsible sections in wiki formatted text, via a macro. This works great in wiki pages, and in tickets, but not in reports.

• Report descriptions can contain wiki formatting
• Report results (e.g. "SELECT foo AS description") can as well
• Yet foldable sections work in neither.

I believe this could be fixed by adding folding.js to the script includes for report pages, and adding "$(".foldable").enableFolding(true, true);" to the jQuery(document).ready({…}) section.
