Flip names operator changed in rB702bc5ba26d5, to some sensible behavior. But this breaks common workflow of 'duplicate part of the bones, scale-mirror new ones, and flip their names'. So now, instead of doing this in two steps, trying to guesstimate which bones should get which name, just add option to flip names to duplicate operator itself. Simpler, safer, and much, much more consitent behavior and predictable results.
