Update for Karma v0.10

angular-requirejs-seed is out of date for the current Karma release, v0.10.  Attempts to run tests produce errors due to the Karma config format having changed.

These changes bring the configs up to date so that the test script runners work, as well as the `karma start` and `karma run` commands.

Finally, the e2e `runner.html` file as documented in README.md was missing.  I've added the HEAD version from angular/angular-seed, which appears to work.
