There are fliphorizontal and flipvertical properties for the breadboard view definition. Set the appropriate ones to “true”. See the Views and layers in the part file format document on the wiki. I believe this has to be done by editing the fzp file manually. I don’t think the Parts Editor has a way to set those, but I seldom use the Parts Editor, so might not know how.
For more extensive information, these two sets of tutorials apply to the current versions of Fritzing (most of the others are for older versions of the software.)
