Content Index v0.8

Description:This is a neat menu/page to display links to all your content.
My site has permanent content instead of reviews, etc. So the recent list just didn't cut it.
* Categories can be expanded and contracted.
* Shows all Content Items in one menu or page

Future Features (if requested):
Choose specific category.
* Language Support
* Content Image Support
* Optional displaying of Author, date/time, etc.

Fixed: config.php file is no longer referred to
Fixed: empty categories aren't shown
Fixed: sub-categories work properly
