Nest Cameras, Pinterest, download Instapaper articles, People & Places compatibility

• NOTE: Update to Keyring 1.7 for full compatibility.
• Enhancement: Nest Camera importer.
• Enhancement: Pinterest importer.
• Enhancement: Instapaper now downloads the full content of articles and stores it within the content of posts, so that you can search them later. It applies a noindex tag to those post pages to avoid duplicate content issues. Note that this is retroactive, so it'll go back and find all your old links and try to download their content over time. If you don't want that to happen, you'll need to set a postmeta/Custom Field against all of them called remote_content (set it to '1'), or you can filter keyring_instapaper_download_article_texts and __return_false to always turn it off; add_filter( 'keyring_instapaper_download_article_texts', '__return_false' );
• Enhancement: Compatible with People & Places (must be installed manually currently) to associate people and places across all services under a single taxonomy.
• Enhancement: Added "Reprocessor" concept (accessible via Tools > Import > Reprocess Keyring Data) to allow developers to re-use the raw import data for posts, and update/reprocess information.
• Enhancement: Bundle Reprocessors to fix an old encoding bug, plus to process Twitter, Instagram and Foursquare imports for People & Places.
• Enhancement: Default the UI to save imported content against the current user/author.
• Enhancement: Link back to the importer on the success screen.
• Enhancement: Add a new filter to the default header (keyring_importer_header_css) so that you can easily inject some custom CSS, without completely recreating the header.
• Bugfix: Remove a bunch of unused global variables.
