[Dependency] Check kano-burner version

[radujipa]

During dependency checking, we should check the version of the burners against a minimum-version reported by the server when retrieving latest.json.

I like this - we can even have the burner update itself when it finds out that it isn't modern enough.

@tombettany I have implemented this. A json file containing "min_burner_version" >3 should caus ethe current burner to exit and advise the user to download a new one.

@alex5imon I tested this myself, so I think it can be closed since there is a lot of other stuff to test.
