* Jetpack: Sync carousel module changes

Summary: @michiecat mentioned today that a client was having an issue where opening a gallery, closing a gallery, and then clicking the back button was reopening the gallery. It looks like we have fixed this in Jetpack, but we need to sync those changes back to WPCOM so our WP.com and VIP users can get those changes.

Test Plan:
Check out patch. Sandbox site. Open gallery. Navigate through slides. Close gallery. Hit back button. Gallery should not open.

**Bonus feature**
Single images linked to the attachment URL should now open in a lightbox.  via #5469
