This PR address a problem in the slycot build process (documented here) in which building slycot from source is currently failing. This is related to issue #349 where coveralls was reporting a decrease in coverage (because slycot was not present => some code was not being tested).

To fix this, I changed the .travis.yml file to use the conda-forge version of slycot by default. This is probably the better thing to do in any case, since that is how most users are likely to get slycot. I also added two "optional" (allowed to fail) builds that create the slycot package from source code, as was originally done. I put in one for python-2.7 (still working) and one for python-3.7 (failing).

I didn't squash the commits when I created this PR, but suggest doing that when it is merged.

The Python 3.7 slycot=source job fails because Travis mixes OpenBLAS with BLAS/LAPACK. See my comment in python-control/Slycot#85
