Allow creation of index pages (0.25)

[gma]

Rather than serve /foo from /foo.{mdown,textile,haml} it would make a lot of sense to allow people to create /foo/index.{mdown,textile,haml}, and to serve /foo from there. Not only would it allow you to keep the main Foo category page with it's relevant content, it allows us to create content/pages/index.haml from which we can serve the home page. The home page belongs in the content folder, not in ./views.

Tasks

• [DONE] Create content/index.haml from nesta new.
• [DONE] Delete views/index.haml.
• [DONE] Delete the route for /.
• [DONE] Update the CHANGES file.
• [DONE] Drop keywords and description in config.yml (they'll be set as metadata on index.haml instead).
• [DONE] Implement title metadata to control page title independently of heading.

[DONE] Drop keywords and description in config.yml (they'll be set as metadata on index.haml instead).

Shouldn't title: "My Site" not exist in the config.yml template, if this is done?

[gma]

Some themes will use the site's title on every page (e.g. in the header or footer). It's also used in the atom feed.
