This enables Apple forcetouch DOM events. It requires the preference dom.forcetouch.enabled.
The DOM events are described here:
- https://developer.apple.com/library/mac/documentation/AppleApplications/Conceptual/SafariJSProgTopics/RespondingtoForceTouchEventsfromJavaScript.html
The Cocoa mechanism is documented here:
