nz-toggle fire only on user event ?

[ptitdje45]

Hello,

can we fire a toggle only on user event, and don't call the 'on-toggle' when model is changed ?

Thanks

Hey there! I've made a Pull request to issue this.
Check here: #44

I had some trouble when using nz-toggle with md-virtual-repeater due to the watch, so I made that it calls onToggle method only when the toggle function was called as a result of user action.
