Suggestion: if no quick check command is defined, hide that stats section #30

When I create a project without a quick check command, I still see the quick check counters which will all stay at 0. Maybe we could hide those from the project page?

As a side note, I first used a quick check command, which is my as2js compiler with the --version. Only that would always exit with 1. So the command worked, but the exit code was misinterpreted. I don't think you should change anything, but it took me a little while to realize that was why the tests were actually never running...
