Merging brands or categories now shows up in the one you keep

A merge now writes a row in the version history of the brand or category you keep. It used to write one on everything else it touched, while the brand you kept still read Created and nothing more, because none of its own fields had changed.

Open a brand or a category, look at its version history, and the What column reads Merged followed by the name of what it took in, or a count when there was more than one.
