1. Add source map support - if a test fails, a stack trace show original location instead of location in compiled .js file. 2. Fix issue introduced by the new version of the Karma IntelliJ plugin. The new version pass test names wrapped in /.../, but karma-mocha doesn't support it. As a result, it was impossible to run single test/suite in IntelliJ without hacking. Now it works out of box. 3. Fix "Browser disconnected" issues in IntellJ. Change-Id: I4c758d6e7e2739ab291857d758aaf642fcd11d54
