Title: Support two-way binding for checkboxes in LinkedValueMixin via 'checkedLink' property

This is an attempt to fix #475.
As per petehunt's suggestion on the issue, I added a new `checkedLink` property for `input` components, that behaves like `valueLink`, but reads/updates the `checked` status instead of `value`.
