Remove all mention of make.osx in README.osx
Allow Animation.save() to accept keyword arguments which are passed on to savefig() when saving individual frames. This can be used to set tight bounding boxes etc.
Don't use a mutable type (here, a dict) as default argument because it only gets evaluated once when the function is defined, not during each function call (i.e. changes will persist across function calls).
