Fixed filtering in component chooser on Windows

Please never ask me about the SetSortOrder() part. When it is set to
'true', wxDataViewCtrl::EnsureVisible() does not always work correctly,
so sometimes the best search result is not shown in the window (no
pattern found). Now it is set to 'false' to avoid the described
behavior, but the sorting order is reversed on Windows, not on Linux.
I could not test it on OSX, but I am sure it paints walls in your room
pink. /me burst into tears.
