Force character encoding for event stream to utf-8

Hi,

This change fixed an "EventSource's response has a charset ("iso-8859-1") that is not UTF-8. Aborting the connection." error in Dashboard for me.

Thank you Mikko for submitting this fix.

Testing looks good:

$ curl -v http://localhost:8989/hystrix-examples-webapp/hystrix.stream
* About to connect() to localhost port 8989 (#0)

I launched hystrix-examples-webapp and hystrix-dashboard using your branch and everything looks good so I'll merge this and release soon.

I appreciate you sending a pull request.
