Update plugin version to 3.1.

Changelog

• Implement Tips Interface to guide a user in the new editor interface.
• New design version of sibling inserter (the ability to insert blocks between other blocks).
• Allow users to re-enable Tips.
• Allow the user to preview changes to a published post without first updating the post.
• Show the preview mode for HTML blocks converted into shared blocks. This streamlines the process of creating straightforward HTML blocks and letting users insert them visually.
• Exclude the currently focused block from the block completer options. (i.e. don’t show paragraph as an option if already on a paragraph)
• Trigger autosave as standard save for draft by current user.
• Add mime type checking to the pre-upload error messaging system when uploading media.
• Allow block hover outlines to draw color from admin theme.

• Remove the usage of the componentWillMount lifecycle.
