Any remarks ?

@ldez thank you for your contribution. I've only glanced it, but I'll be looking at it soon.

@magbicaleman now you can activate CI with Travis CI and AppVeyor
Can you publish a new version ? (apm publish major)

[magbicaleman]

I have Travis CI activated (failed), not yet with AppVeyor. I'm assuming the AppVeyor CI, is to test out the plugin in the windows environment.
