When converting a thread to an item, the reactions will now also be moved over.
Sorry, 1.0.3 had the wrong template.
Better logic for template replacement (so as not to clash with other mods)
Don't show "Add Item" button to guests
Removed un-necessary database query
Schoolboy error - hide first post now works correctly
Only load updates for posts on current page.
Added index for item_id & discussion_post_id.
Renamed template incase it clashes with a future Showcase update.
