Hide when scrolling?

[RaduGrama]

Is it possible to add functionality to hide the button while scrolling and display only when the scrolling stopped?

Hi, right now these are the implemented options:

MEVFloatingButtonDisplayModeNone , MEVFloatingButtonDisplayModeAlways and MEVFloatingButtonDisplayModeWhenScrolling

It wouldn't be difficult to implement since that option would be just the opposite that the mode MEVFloatingButtonDisplayModeWhenScrolling

Feel free to send a pull request and I'd love to merge it.
