Many components in the appfilter.xml have duplicates, so I suggest finding a way to automatically remove them.

I think icontool.py now checks for alphabetical sorting at runtime and fixes it. This will work with duplicates as well. If the lines are identical, leave one. If the components are identical but have different names or svg, somehow inform about it (not sure if the current check in icontool.py works that way).

It will be cleaner.
