Added support for commonJs (npm/browserify)
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.
add appendDots option

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

Fixing chrome mobile pan bug
Unset width on destroy & unload, instead of removing style attribute
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`.

Progressive Lazy Load option fix for 404 requests

Currently if a image 404's or has any other error then the .load callback is never called, which means the recursive function stops right there. This proposed change is to handle any image error and continue loading additional images.
