Create a testing suite that can be ran on the desktop/CI server

[sattvik]

I wrote tests years ago, but now they are all disabled. We need to develop a strategy to get them working again.

I left the test/ folder from the original Neko untouched. I just haven't used those tests, so I never checked if they still work.

I agree that we need testing, but it should be device-independent like RoboElectric. Something we can put onto Travis or other CI.

[sattvik]

I agree. I've started thinking about it, but it will take some time before I have a workable solution.

Renamed for clarity.
