Built into SciTools user, rather than pelson.

This changes over the upload channel from pelson to SciTools.

I've tested that the upload would work for both Linux and Windows by pushing the branch to scitools rather than my own fork (travis: https://travis-ci.org/SciTools/conda-recipes-scitools/jobs/44379789, appveyor: https://ci.appveyor.com/project/pelson/conda-recipes-scitools-311/build/1.0.15 (not yet complete))
Good luck reading the diff of a diff file. Essentially, the patch file no longer worked on OSX (I don't know how it got borked). I noticed this when the travis-ci tests re-built everything and this failed.
