SavePlatform implementation

Before refactoring the whole Communication protocol, I implemented the save platform request/response for the demo. 

IT'S NOT THE FINAL IMPLEMENTATION, but it's a working one and it's good enough for us now.

Please, stop messing with ip and port in data.json.

I'm sure that know, I don't need to tell you that you need to
1. npm install in uCtrlSimulator
2. npm start
3. Uncomment Simulator section in main.cpp and comment file section
4. Start application
5. Make changes and see the magic!

Tested and working on Wintoo and Macintosh OS.
