checkbox: clicking links in labels also toggles the value

[nikclayton]

Actual Behavior:

• What is the issue? * If an md-checkbox has a text or a label that contains a link, clicking the link (either with _target="blank" to open in a new tab, or Ctrl-click) also toggles the checkbox.
• What is the expected behavior? Not toggle the checkbox. This is the behavior of the native <input type="checkbox">.

This is related to https://github.com/angular/material/issues/11134, which can't be fixed until 1.2.0. I need to investigate whether this can be fixed prior to 1.2.0.
