Fixes

Fixes #194 by @zackkrida

Description

This PR creates the NoticeBar component for showing notices and uses it to show the MigrationNotice component on the top of the page.

Technical details

The notice is shown on first render and disappears after you navigate to a different link. This means that the code for this is split across a plugin (plugins/migration-notice.js) and a middleware (middleware/middleware.js).
