Implements NOISSUE: Disables changing input type="number" element by mousewheel

Sign-off: @mumia 

Since some of the uniplacers operators uses touchpad, I created a directive to remove the value change in a input text="number" element (this is only applicable on webkit browsers like Chrome). 

So the person doesn't have to blur() when scrolling, because if he wants to scroll down, the directive will do a blur for him, instead of changing the value of the current selected input type="number" element.
