Fix crash when examples are in multiple categories

Browse Source 
When items are added into multiple categories, we got into a double
delete when cleaning up, e.g. when changing the shown examples to a
different Qt version.

Sort copies into categories and delete the originals as a quickfix.
Cleaner would be if we didn't allocate them on the heap in the first
place.
