Wren 0.3.0 "Hiemalis"

Two features, one release:

Static homepage and articles page. In Settings, point Homepage shows at any published page and it becomes your front page — turning Wren from a blog engine into a small-website engine. The article list moves to its own menu entry with a configurable name and address (default: Blog), pagination intact, and the homepage's old URL redirects to /.

Per-page title visibility. Pages gain a "Show title on the page" checkbox — untick it for a clean front page that doesn't display its own name.

Also introduces automatic database migrations: upgrading remains "replace index.php" and the database updates itself on the next page load. Upgrading from 0.1.0: replace index.php — your database and theme carry over untouched.
