When route changes via link, should start at top of document.window.

Scenario: Click on a :username hyperlink  (in comments or in following list) somewhere other than the top of the document.window and you'll notice when rerouted to the new view it stubbornly persists in same window location. Need some sort of go-to-top-of page-upon-entry thang.

(Note: this doesn't happen if you click on the :username of the post)
