Tooltip is visible after "click" when event is "hover"

Small thing.
When tooltip is shown on hover, after click event he is simply "hanging" there.
Proposal would be to bind click anyway when hover is used

``` javascript
@$element.hover((=>
    _hover = true

    @updatePosition()
    setTimeout(=>
        @show() if _hover
    , @getSetting 'delay')
), (=>
    _hover = false
    @hide()
)).bind('click', =>
    @hide()
)
```
