Add sidebar menu items for /site/docs/list and /site/docs/edit. They do not currently have view functions attached, but there are other links in the mock-up portion of the sidebar that don't currently work, either. The goal is to commit the /site/docs/list and /site/docs/edit changes in small bits that don't break anyone else.
