velocityX/Y is NaN

[Draeli]

I was trying to use your other plugin "jquery.event.swipe.js" and find velocityX/Y return "NaN".
Digging more, I come inside "jquery.event.move.js" and find when "updateEvent" is call, "timeStamp" is undefined and has side effect to false all calculation after about velocity.
Digging again, I was trying to solve this adding "timeStamp" on "event" (inside "movestart" function) but browser throw a "TypeError: setting getter-only property "timeStamp" (which is not a surprise).

In desperation, I corrected by setting a new parameter to "updateEvent" :
function updateEvent(event, touch, timeStamp, eTimeStamp) {
and for the call :
updateEvent(event, data.touch, data.timeStamp, e.timeStamp);

I'm sure this is not the best solution but at least it does the job ^^
