Fix travis, work around appveyor build breaks

Benoit Hudson · filmor · commit 8a9fd73200f8 · 2018-10-12T21:27:56.000+02:00
Travis now has msbuild 15 available, which breaks the no-arg build since it's using the pythonnet.sln which is msbuild 14. Fixed by forcing the use of msbuild 14.

Appveyor on py34 is failing to build psutil; newer python and py27 are using binary releases so the problem doesn't show up. I couldn't figure out how to fix it, so I made it an allowed failure.
