Fix touch handling when using jQuery

When using jQuery, events seem to get "fixed" to work around some browser bugs, but this doesn't work perfectly for touches. See (http://www.the-xavi.com/articles/trouble-with-touch-events-jquery) for more details. This meant that if someone used orbit with jQuery rather than zepto, touch handling would be broken due to e.touches being undefined.

This fixes that case.
