Input control templates should remove element attributes from the outer div

[hxu]

The template for the input control copies attributes from the directive to the inner input tag, but also leaves it on the outer div. It should remove them instead, so that the attributes are transferred to the tag.

More generally, I need to decide which attributes get moved to the internal input, and which ones get kept on the outer div. For example, in some cases we may want a class to be kept on the outer div.
