servo: Merge #9811 - forcetouch events (from paulrouget:forceTouch); r=mbrubeck

https://developer.apple.com/library/mac/documentation/AppleApplications/Conceptual/SafariJSProgTopics/RespondingtoForceTouchEventsfromJavaScript.html

Not sure how we want to land that yet. Maybe reproduce the webkit events (as in this PR), or as touch/mousemouse events.
