[Ifeffit] Larch 0.9.33

Hi Folks, We've released and uploaded Larch 0.9.33. This have been many small fixes and improvements over the past year or so, including significant progress on handling X-ray diffraction data from X-ray micro-probes. There have also been improvements in Python 3 support,so that almost everything now works in both Python 2.7 and 3.6. The "server mode" for Athena and Artemis now works on all platforms and I strongly encourage everyone to use this over the ifeffit back end. Progress has been made on the xyfit app, a peak fitting GUI. It's not complete, but any feedback on functionality or usability at this point would be greatly appreciated.
