I broke travis

[orbeckst]

I think as part of PR #2231 I broke travis... since then I can't run Travis jobs, probably messed up .travis.yml.

Working on it...

$ travis lint ../.travis.yml
Warnings for ../.travis.yml:
[x] syntax error: (<unknown>): found a tab character that violate intendation while scanning a plain scalar at line 50 column 12

The docs build fails on Travis at the moment, as far as I can tell. I thought this had something to do with building in a py 3.5 environment and updated the doc build to 3.7 as part of another PR. I thought I fixed everything because the CI status was green. However, Travis did not even run, but AppVeyor did, and that was enough to green-light. (First lesson: a green check mark is not enough, one actually has to look at what ran!)

I had made a mistake in the travis.yml file by introducing a TAB. D’oh!, see #2233 ; the corresponding PR fixes that.

However, docs still don’t build, see e.g. https://travis-ci.com/MDAnalysis/mdanalysis/jobs/189877496 ; the error message is

If anyone can help then please do. I’m busy/travelling the rest of the day so ANY help is greatly appreciated. Use #2233 and PR #2234

The problem seems to be with sphinx. sphinx-doc/sphinx#6225
