Extend the info block of the report with the number of passed/failed tests

[CzBalti]

I would suggest something like this:
info: { "...": "...", results: { "all": "10", "pass": "9", "failed": "1" } }

On the develop branch this is done now, but it's not part of the info block, since this is not supposed to be automatically modified.
