should dispatch "slideend" on click

[tra]

When clicking on the slider, the slider moves to the new position but does not dispatch a "slideend" event.

I wanted this feature as well. I don't know that everybody would want it, but it was definitely awkward having the data update when the slider is done being dragged, but not when clicked to a new position. You can get this if you dispatch "slide", but in my case it didn't make sense to update the data as frequently as that - I have a comparatively small step compared to the range of the slider, so it is essentially continuous.

For others who may want this, I did get the functionality I wanted by adding:
dispatch.slideend(d3.event, value);
to the end of the onClickHorizontal() and onClickVertical() functions.

I could see this as an option to turn on or off, and I could also see making the click event itself optional. It depends on how you want to direct the user to interact with the data.
