Should specify relative page paths using `page-href`

[finnsson]

<div data-bind="page: {id: 'start'}">
  <!-- This will update href to #start/bender -->
  <a data-bind="page-href: 'bender'">Bender</a>

  <!-- This will update href to #admin/login -->
  <a data-bind="page-href: '../admin/login'">Admin Login</a>

  <div data-bind="page: {id: 'bender'}">Bender!</div>
</div>
<div data-bind="page: {id: 'admin'}">
  <div data-bind="page: {id: 'login'}">Login</div>
</div>

Based on the total path of the page the binding calculates an absolute href.
