Title: Adds support for checkbox arrays

Checkboxes can now be given an identifier terminating
in `[]` to denote that the value attribute should be used
as an array key. For example, given the following form

the model binding would generate an array `Model.foo = ['baz']`

Setting the value to another array updates the checkbox states, so

Model.set('foo', ['bar'])

would produce

in the view.
