Post Gate v1.2.2

Fixes a console error that appeared on the single-post editor.

Bug Fixes

• No more inlineEditPost is not defined - the Quick Edit JavaScript that extends the post-list inline editor is now only emitted on the post-list screen (edit.php). It is no longer printed on post.php?action=edit, where inlineEditPost doesn't exist and the reference threw an uncaught error in the browser console.
