Add fields for customization Blynk host (#1543)

* Add fields for customization Blynk host

Add fields to 'Sync Interfaces' for customization Blynk host.
Now you can set you own Blynk server.
All you needs its set custom host and port to local Blync server.

* Lower blynk host length (memory usage)
