Title: Picklable figures

I have been working on the ability to pickle figures (as mentioned in #323).

I have done quite a lot of testing of this (pyplot figures, non-pyplot figures, polar axes, contours, pcolormeshes etc.) but it is inevitable that there will be some types of plots that simply do not work at this stage.

There was a little (backwards compatible) shuffle in the way pyplot creates its figures which will need applying to all backends, and some unit tests will need adding, but other than that, I think this is in a form where it is worth getting other developers eyes on the code.

Any questions, please ask.
