Feature request: setting hostname

[ettom]

Hi, this is a feature request to allow setting a hostname. Good arguments for hostnames are OTA updates and general clarity when multiple devices are on the same network.

I've implemented this for ESP8266 and it's working well so far.

You can do this manually in your sketch. Sorry, I see no reason why this should be part of Blynk library.
