Review request for kdelibs.


Changes
-------

I've fixed whitespace and indentation. But I couldn't find a good way to use the code from QStringList_removeDuplicates however as my code is quite different and doesn't actually involve duplicates, only mimetypes that can be interpreted as duplicates. From my tests it seems to be quite fast already and besides it doesn't run very often, only when kbuildsycoca is run which happens in the background.


Description
-------

This fixes a bug introduced by https://projects.kde.org/projects/kde/kdelibs/repository/revisions/871cccc8a88a600c8f850a020d44bfc5f5858caa that made it impossible to re-order file type associations both in System settings and in the open with list. Hence it contains a new way of detecting duplicate (inherited) mimetype entries, that the original was supposed to fix.


This addresses bug https://bugs.kde.org/show_bug.cgi?id=321706.

Testing
-------

I have tested so that file type associations can be ordered correctly, in addition to making sure that parent mimetypes have precedence when an app lists two or more mimetypes where one is the parent of the other.


Thanks,

Mathias Tillman
