Use less verbose test output formatter

[eugenk]

The quite verbose formatter annoyed me a little because it printed way more information than we needed. This pull request adds formatters that combine the strengths of the very verbose formatters documentation (for rspec) and pretty (for cucumber) and of the too little printing formatter progress.

Those are only active by default on development machines. I made sure that the verbose formatters are used on travis and jenkins.

rspec

cucumber

Mhm, per default i would only activate the middleground for rspec (where it is really necessary). For cucumber i think that the verbose output is actually necessary/extremely useful.

I think verbose output in cucumber is only useful when something fails. Otherwise it's just some green text that you don't read anyway. At least I don't.

In my opinion it clutters the console. We don't have that many cucumber features at this point, but when it gets more, I think we really want to shorten the output.

Yeah, but you do not get the full output for a failing test, and i think for cucumber (with their step-system) it is important to see them all.

@ebolloff want to be the tie-breaker?

[eugenk]

Yes, then I think I should change the formatter to print the full output of a failing test.

[0robustus1]

If that would be possible, it would probably be the optimal case.

How about now? a44c794 "Print failure details after the features." should add the details.
