 Index navigation improvements:
  - You can now refresh the index page you are on with the icon in the header bar or the same keybind for refreshing threads.
  - You can now switch between single-page and all-pages navigation via the "Index Navigation" header sub-menu.
+ - Threads in the index can now be sorted by:
+  - bump order
+  - creation date
