Subject: [PATCH] [Misc]Improve navigation on mobile devices (#639)

- Make the sidebar useable again
- Add the search field back and move it to the top
- Move the category navigation tree from the content area to the
  sidebar, preserving the hierarchy

These changes have no effect outside mobile mode (width <= 992px).

Fixes #487.
