The stock Android browser doesn't support the current for-in body/style
detection for animations and transitions but we can manually fix this.
This is useful for PhoneGap web-views or traditional web-apps using the
stock browser.
window.SecurityPolicy.isActive() is now window.securityPolicy.isActive
since this is available only in Chrome Canary which has already been
updated, we can safely make this change without worrying about
backwards compatilibty.

On IE9 the input event is not fired when backspace or delete key are pressed or when
cut is performed. This makes listening on the input event unreliable and therefore
it's better for us to just use keydown/change events instead.
