Blynk app integration with Node Red

Websockets version

Due to some reliability issues reported by some users, together with some new features added by the Blynk team, I started another version of this based on websockets. Currently it only works for local servers but it is so much faster and reliable that I am considering packing this one and continuing work only on that one. I have not added it to npm yet, but you can find it in the repository below until I decide what to do and get some reports back from testers. If you would like to help, please test it
