Make progress formatter show its output immediately

[kfischer-okarin]

When I use the default progress formatter my terminal will output nothing unless a newline is included.

Maybe that's a problem of my terminal settings or my OS (using MacOS).... but other test tools work just fine in that regard. (Ruby's RSpec for example).

I fixed that problem by wrapping the puts method of clint (which seems by the way not to be maintained at all anymore - the GitHub repository is archived) and always flushing the stdout stream

Going to check this stuff this weekend.

Thanks for your patches and your patience.
