Qt: About Dialog move to QTreeView and fix copy

- Fix an issue, where the url was opened twice on Linux
- Make the filter case insensitive if so wished for
- Allow the copy to either copy the selected column (just Copy) or copy the complete row, with tab separation
- Move to QTreeView instead to make it similar to the rest of the tables
