Title: Mpl toolkit pep8

pep8 clean up on files in mpl_toolkit.axes_grid1

mpl_toolkit does not currently get tested for code compliance, only the matplotlib namespace is. Do we want to test mpl_toolkit too?

Made a few non-formatting changes. Removed some mutable default arguments and change `foo == None` test to `foo is None`
