Natural language for symmetrical brands (ready for merge)
I don't really like choppy writing, and I admire the way longSlaveDescription tries to make sentences instead of just dumping blocks of data.
That said, certain things can quickly get very choppy (piercings somewhat, some tats, and now brands with multiBrand.)
"She has an X in her Y"
"She has an X in her Z"
"She has an X in her AZ"
...etc.
I have made a new function, oppositeSides, that will help me out if I ever work on other bodymods in other areas, but the main idea here is to be able to handle different situations in one natural sentence. Say her hands have no brands, one brand, two matching brands, or two mismatched brands.
Well, we can handle that now.
edit: small addition. Though I currently updated things so there are no attempts to looks for "left hand" specifically, I improved the function so if it ever receives such a request, it will return the old functionality.
