SpaceAnalyzer: Partially address code review changes. - Use GUI::CommonActions::make_about_action(). - Pass large arguments by const reference instead of by value. - Mark const functions as such. - Add newline at end of SpaceAnalyzer.af - Use full words instead of abbreviations in variable names. - Use application's namespace instead of 'TreeMap'. - move() certain assignments. - Use member declaration initialization. - Initialize TreeNode* member of QueueEntry. - Rewrite find_mount_for_path to return MountInfo* instead. - Rename ITreeMap and ITreeMapNode to TreeMap and TreeMapNode. - Replace ext suffix with rect suffix for rectangles. SpaceAnalyzer: Further address code review and coding style. - Remove get prefix from accessor functions. - Layout algorithm in its own function, with callback. - Remove nullptr comparisons. - Store lstat errors in error_accumulator. - Use Rect::shatter. - Use Rect's orientation based functions. SpaceAnalyzer: Make sort_children_by_area const qualified.
