revamp the way page:treehouse/new works

Browse source 
- treehouse/new is now a regular page, not a special template
- most of the code related to the `new` badge in page:index has been removed
- you're meant to discern between pages you've read vs ones you haven't by looking at the colors of the links (blue vs purple)
