v0.2.1

Initial release: v0.2.1

Show a FeedLand river -- a constantly-updated stream of news from the
feeds a FeedLand user subscribes to -- on a WordPress page or post.
Fetches the river JSON from FeedLand's API server-side (cached),
renders it with its own template, and embeds the result in an
isolated iframe: no FeedLand front-end scripts, no third-party
stylesheets, fonts or scripts beyond an optional feed-favicon lookup.

Full development history retained locally under the
v0.2.1-dev-history tag.
