initial work on /codecamp
removed dormant routes

Some routes are useless now so I took them out by commenting them. For
most of them (if not all,) their controllers still hang around. Maybe we
could use them for something else. It's a gargantuan breach of YAGNI, I
know
layout for codecamp only
CodeCamp now has a different layout than all pages
removed dead routes

routes contained dead routes (some commented out). I removed them along
with their controller actions.

set_title
