Mateusz Uzdowski f4b080ee06 NEW Side by side editing functionality - first cut (os#7412)
Introduces a preview window that appears when the screen is wide enough,
removes old preview button, adds a draft-public switch, adds variety of
preview options which are not hooked up yet.

Goes along with cms commit fa3738a9f4c5181eabf18a77ca89792d31592250
