Two navigation fixes, both of the sort you only notice when they are wrong.
The sidebar lost its scroll position on every page navigation, so readers deep in a long tree were thrown back to the top each time they followed a link. It now persists.
The second continues the base-path thread from 0.2.0: relative asset and page URLs now resolve to base-absolute clean URLs. Relative links appear to work right up until a page moves depth, or the site moves under a sub-path — the exact case 0.2.0 introduced.
