Remove DOM ready listener from docs, upgrade `react-router-component`

Removed the need for the DOM ready listener by moving the script tags
to below the HTML.
Updated `react-router-component`, this has no effect on this projects
implementation.
Changed `NavMain` links to be absolute, this is consistent with the pages
definition.
Remove console statements from built code.

Not sure how these slipped through, but remove them before someone
notices :P
