Add options.dieOnError

[jimthedev]

Fixes #23 by adding an option to not throw a plugin error.

+1 any reason this hasn't been merged yet?

+1 this makes a lot of sense. However, gulp-karma will be refactored into more of a helper soon. See #21 (comment) for details.

@jimthedev and @akreitals, one question: Have you tried adding an error listener on the stream? That should stop it from dying.

[jimthedev]

@lazd I think I did, and it would catch the error but still end the stream in certain cases where there was a parse error. With this said, it has been long time since I looked at this so I'm not 100% sure. I don't actually have the branch which used gulp-karma on my project anymore. We're currently using grunt still.

[akreitals]

@lazd Yeah sure did, but with no success unfortunately. In the interim I have simply implemented the dieOnError option while we wait for the Karma issue to be resolved.
