Not all reporters support recursion.

Just started using nodeunit. It seems not all the reporters support the recursive option.

It seems `recursive: options.recursive,` is missing from the call to `nodeunit.runFiles()` in at least eclipse, html, junit, minimal, nested, skip-passed and verbose.

I can see where the missing option is missing from lcov and machineout, but in my limited testing, I couldn't see a difference ... or ANY output!

I have amended my installed nodeunit and get the recursion as expected.

I can create a patch (https://github.com/caolan/nodeunit/pull/348), but I'm not sure about proof/testing. Ideally, I'd like to know how to add tests to prove that the recursion is operational, but if the fix is correct and a super obvious oversight, then maybe it wouldn't be necessary.

eclipse、html、junit、minimal、nested、skip-passed、verbose reporter における nodeunit.runFiles() の呼び出しを調査し、lcov および machineout と比較します。まず、既存の reporter テストが recursive runs をどのように実行しているかを確認し、次に、対象となる reporter 全体で recursive option が尊重されることを示すカバレッジを追加します。
