add swipeState

added a boolean to keep track of the swipe state.
if your swipe able elemtents are clickable - the click would always be fired

with this addition the click can be intercepted like:

```
$("#my_elems").click(function() {
             //FIX FOR WP
             if(typeof(window.navigator.msPointerEnabled) != "undefined" && typeof(window.mySwipe.getState) == "function" && window.mySwipe.getState() == true) {
                       return;
              }
         
		
});
```

the following CSS is also usefull (atleast in my case :))

```
* {
-ms-touch-action: pan-y;
}
```
