Add switches to keep announcements off a page or off post pages

Announcements showed on every public page. Now each page has a "Show
announcements on this page" checkbox (pages.show_notices, on by default)
that covers the page and its posts, and the Design tab's Content section
has "Show announcements on post pages" (theme.post_notices, on by default)
for bloggers who want notices only on listings, not while reading a post.
