Subject: [PATCH] Remove change event on old element when re-initializing
 selectify

Call el.off("change") if .data("sl") is true.

I have two selects on my page, and need to change the available option in the second select based on what's chosen in the first select. After an option is chosen on the first select, I call .selectify() on the second select to update its list of items.

This alteration ensures that we don't hook up two "change" events to the same element if selectify() is called multiple times on the same <select>.
