Add announcements: blog-wide notices on every page and post

A blog can have any number of announcements ("sections" in the schema):
a book club's next meeting, this month's pick, a holiday closure. Each
has a placement (above or below the posts, or under the menu when the
menu is a left sidebar), a look (highlighted, warning, plain), an order,
and an on/off switch so recurring notices can be kept around while hidden.
