[IPython-dev] Breaking change to KernelManager.start_kernel?

KernelManager.start_kernel used to take a ipython keyword argument, but it seems that this has disappeared at some point in favor of the launcher argument.

Looking at the code it seems like if I don't pass this on .11 (and .12 too maybe?) then I'll get the pykernel launcher and on .13 I can just pass nothing and get the ipkernel.  It seems like the best option to support multiple versions is to check IPython.__version__ and just make the appropriate option.  Anyone else have any other ideas or suggestions?
