Label of button should read scheduled on quick edit posts when future date set

[TheCellarRoom]

quick edit a draft post and set the date to any future time, the button says 'publish' rather than 'schedule' as it does on the main edit post page.

possibly related to : #19907 #8529

clarity: it's the 'publish' in the drop down box for status that should read scheduled the button says 'update' all the time.

Makes sense to me.

Proposed patch updates the following:

1. inline-edit-post.js: new updateText function (copied and modified from the one in post.js), updates the drop down item to either Scheduled or Published
2. class-wp-posts-list-table.php: has a new hidden div storing the current date and time, used by the inline-edit-post.js updates
3. script-loader.php: added 'published' and 'scheduled' to the localized inlineEditL10n object.

While working on this, I noticed that when quick editing a scheduled post and setting the date to something earlier than the current date/time, the drop down still says Scheduled until you click Update, even though the post gets published. We could offer a little better visual indication that the post will be published if we change the drop down to say Published when the time is changed before clicking Update.
