Title: Adding the ability to teardown the placeholder plugin on an element that...

... previously had set it up. The intent is to restore the element to its state before calling the plugin.

This is similar to how jquery ui plugins provide a destroy option. It would look something like:
```
$("input").placeholder()
...
$("input").placeholder('destroy')
```
