Fix AppVeyor and Travis UnitTests

[bp-kelley]

UnitTestSimilarityMaps was failing on travis because no XWindow display was set. This forces matplotlib to use the Agg renderer when the DISPLAY variable isn't set which allows the test to pass but perhaps has side-effects.

This was the reason the travis python 2.7 was failing I believe.

I think the python 2.7 build on travis-ci is failing because some tests (that are not executed for python 3.4) are now requiring pandas at build time (it was used to be optional).

I'm fixing this as well, the X-display was on my VM so I just fixed it
first.
Interestingly, the travis build is installing pandas 0.17.0 so I'm
investigating why this is failing as well.

the pandas version location changed in 0.17. We should use version not
pandas.version.version

Pulled in riccardo's fix to make this a roll up for appveyor and travis builds. Cross your fingers!

Yay! Appveyor is back to the land of the living :) Thanks @rvianello!

Thanks for tracking that down @bp-kelley!
