Update README.md

## What?
I've added a script on how to automatic boot vnc-version container in `README.md` file for better usablility. For more background, see ticket #83 .
## Why?
Because the script provided in the readme file didn't work on vnc-version container.
## How?
## Testing?
No automated tests, take my word for it ;)
