AUI-1161 - Aui-search-button should follow input on window resize and when moved in dom

Hey Iliyan,

The search cancel button should update on browser resize, but I couldn't write a test for this because I couldn't find a way to simulate window resize. The default behavior for modern browsers is to disable this, let me know if you know of a way around this and I will update the tests.

Thanks,
Patrick
