Don't print coverage report of multiple browsers combined at the end

Have a look at [this build](https://travis-ci.org/julmot/jquery.mark/builds/119779479#L2499) on Travis CI. A test is running on Sauce Labs and all specs (spec-reporter) are printed to the console in the correct order. However, the coverage reports are listed combined at the end. Therefore if I want to know which coverage report is related to which browser I would have to count the position (which I don't like). So isn't there any way to print the coverage report directly under the spec report?

May be related to #195 (the title indicates this issue, but the description is confusing)

Start with the linked Travis CI build and its Sauce Labs browser run, then inspect how the spec-reporter output and coverage reports are emitted. Compare the current combined coverage output with the requested per-browser ordering. Done means each browser's coverage report appears directly beneath its corresponding spec report.
