As per changes in core:
* Use new #this.setAnnotationFromValues method.
* Inline 'initialize' in constructor.
* Bring over 'Change language' button.
* Rename 'Change language' button to 'Find language' and
move to top of form so that it's obvious it's not just a submit
button for the form.
* Properties -> local vairables.
Depends on If121603b5637 in core.
