Add Warnings when wine Version Lower than 1.6

[evshiron]

I was using Travis CI to do automatic testing and suddenly everything failed after the required wine version grew.
By digging into the logs I discover the wine version used is 1.4, but after I switch to ppa:wine/wine-builds and winehq-devel 1.9, the situation doesn't change. I fix this by fixingrcedit version to 0.5.0 in package.json. But a warning will always be a good thing.
BTW don't think this is a minor change.

Wine 1.6 is pretty old at this point so I don't think we need to do this anymore.
