Added python 3.5 and 3.6 as targets

Seems like it will fix #274 as well.

How do you propose to fix the build error for python 3 and qt?

[jwiggins]

See #281. I'll merge that soon and then this branch will need to be rebased/adapted

[jdeschenes]

No problem. The changes in this branch are very minor.

[jdeschenes]

Is there any reason why pyqt is not tested during the travis CI run?

[jwiggins]

I think that's a relic of the days when it was thought that PySide would be the Qt binding going forward.... but don't quote me on that.

[jwiggins]

This should only need an update to .travis.yml now that #281 is merged

[jwiggins]

LGTM!
