Coverage reports for unit tests are empty

Yeah, I haven't made the effort to do coverage reports yet, but I'll see if I can get to it this weekend.

Merged in changes to get coverage working. Works on autoWatched testing as well. The coverage files will save to a coverage directory using HTML & lcov output. The lcov file is lcov.info, the rest of the files in the coverage directory support the HTML output.

For existing projects consult the above commits for changes. But here are the highlights:

• karma.conf.js
  • require('karma-remap-istanbul') replaced with require('karma-coverage-istanbul-reporter')
  • remapIstanbulReporter replaced with configuration for coverageIstanbulReporter
  • In reporters list, karma-remap-istanbul replaced by coverage-istanbul
• package.json
  • Pointing angular-library-set to the GitHub project for now @HEAD
  • Removed/uninstalled karma-remap-istanbul and sourcemap-istanbul-instrumenter-loader
  • Added/installed istanbul-instrumenter-loader and karma-coverage-istanbul-reporter
• Added tsconfig.test.json as the TypeScript configuration for tests
• webpack.test.js loaders were updated to:
  • Point to tsconfig.test.json as the TypeScript configuration
  • Utilize the istanbul-insrumenter-loader
