Scroller forcing x/y position to 0 when setting hScroll = false

Within iScroll there is a hard set value of 0 in the ```_poz``` method when evaluating ```this.hScroll```. So instead of setting that 0 value, if ```this.x``` or ```this.y``` are used then it maintains the coordinate of the current state of the scroller. This seems like it would be expected behavior unless I am overlooking something which is totally possible. Also, thank you for this awesome library and for all the hard work put into it.
