Add Discard option to Save and Close in edit mode

When editing a page, it would be beneficial to be able to consciously discard the draft. Often the user realizes that the changes were absolutely not needed, but has to go through a further three-step process (either re-editing, clicking Discard then clicking Save or going to the profile drop-down menu, selecting Drafts, then clicking Discard by the page).

Even if there is a Discard Verification dialog box to click through, it would be a much better solution.
