flip and rotate with unrooted layout

I really like what you have done here!

Not sure if this is a bug or a feature request, but the flip and rotate functions don't seem to work well when layout ='unrooted'. I get overlapping lines. From a quick guess, it looks like the parents are set up differently for these layouts?

Please let me know if you would like any more details, such as an example nwk file and code.

Thanks, ryan

flip and rotate are currently work with 'rectangular' and 'circular' layouts, but not 'unrooted'.
