Close button on Q.slider

[matt vella]

Hello-

I had the need to add a 'close' button to the Q.slider class. I was
able to accomplish this pretty easily by copying the closeButton class
defined for the Q.window class and adding it as an option in the
Q.slider class.

I could clean up my code and submit a patch, but I don't know how
helpful it would be for you as you have probably changed things around
quite a bit for the next release.

Would you consider adding this option officially for the next release?

Thanks!
Matt
