Build fails on Travis, but not locally

[wasnotrice]

There are 24 failures, all with the same error. Here's an example:

Failures:

1) SwtShoes::App Shoes::App shell receives open
Failure/Error: subject { Shoes::App.new }
NativeException:

I think this might have to do with the TravisCI build VM not having DISPLAY. See https://bugs.eclipse.org/bugs/show_bug.cgi?id=119156#c1

We need to figure out how to use a headless display in travis.

SWT will fail if the window methods can't connect to a display device
