Add onSetPosition callback

Consider adding a callback for setPosition.  I've used this to move buttons and dots based on slide contents/heights.
Add waitForAnimate option

Default behaviour of slide transitions is to ignore all requests to
advance the slide while animating. This option allows that default
behaviour to be modified.

This option is especially desirable when using the javascript method
slickGoTo(index) because the default behaviour causes calls to
slickGoTo(…) to be dropped if it is in the middle of an animation.

- same exact option as appendArrows, except for the pagination
  dots. Change where the navigation dots are attached.

Improve Selector Search for asNavFor and focusOnSelect

Clicking on slides for a slick instance with `asNavFor: true` causes the index lookup to resolve to `undefined` when the `.slick-slide` contains child elements.

This fix continues up through the parents of `event.target` until it finds the DOM node with the `slick-slide` class instead of requiring it be the immediate parent of `event.target`.
