v0.6.0 — Stack traces for Mocha adapter.

In this release, we upgraded the Mocha adapter to log test failures to the console.

In previous version, when there is a test failure, the report shown in the browser window does not contain original source file information (because it does not have access to the source map).

In this version, we also log test failures to the console. This allows you to use your devtools to look at the stack trace, which contains the source mapping.

Hope this release will make your test workflow more enjoyable :)
