Added documentation to inline-edit-post.js

[jjcomack]

As part of Yoast's continous efforts to improve the JavaScript documentation, this patch adds documentation that was missing in inline-edit-post.js.

Props to @rensw90 for doing this.

Hi @jjcomack, thanks for the patch (and thanks to @rensw90 as well)!

For easier review, could you attach the .diff file itself, not in an archive?
