Update karma.js

[MrP]

using Windows, the paths may look like this: aaaa\bbb\uuu
And Js gets confused because of the \u.

Please add a unit test for it.
I think we should just escape any backslash (not only \u).

Also, make sure to follow karma-runner.github.io/0.10/dev/git-commit-msg.html and then squash everything into a single commit.

Thank you for help @MrP !

Thanks for the feedback! I was away on vacation, I'll get to it soon.

Hi,
I created a new pull request #932 with the single commit. I didn't manage to rebase and squash the ones already here.

Is that the way it should be done? If not, could you point me to some guide on how to do it right?

Thanks,
Victor
