Comparing pdf output in tests

Thus, the call to savefig() would continue not to explicitly set the
extension. I've quickly modified the source to reflect my idea, but I
haven't had a chance to flesh it out or test it. It should show the
idea, though. See attached.

I committed something based on this, and a new rc parameter
savefig.extension that sets the filename extension when you call savefig
with a bare filename. The pdf tests seem to be working, at least for me,
but I am sure that the code can be improved.
