Thanks @willschlitzer! There's a few changes I'd recommend reverting since they don't affect the tests (not sure why the hashes are different, maybe due to slightly different systems). Otherwise, there's just one xfail to remove in test_basemap.py and we should be good to merge.

Cool, I'll merge this in (using admin privilleges) and we can handle #1292 to get all the tests passing again!
